NCEI, the National Centers for Environmental Prediction (NCEP), and the GeophysicalFluid Dynamics Laboratory provide remote access to high-volume numerical weatherprediction and global climate models and data.
I needed hourly historical data for my zip code for heat pump comparison. NOAA only had data for 2 cities in all of NY and neither were relevant. I tried to use one of them anyway and also found lots of -9999 temps in each year for which i assume is when there were outages. Also, the reports were in a horribly unusable format with space-aligned columns rather than using something more easily consumable like CSV.
Daily summaries of past weather by location come from the Global Historical Climatology Network daily (GHCNd) database and are accessed through the Climate Data Online (CDO) interface, both of which are managed and maintained by NOAA NCEI.
Historical wind data is a common weather measure that is very important for many applications including business and personal planning. Whether you are looking for wind data related to a specific storm, trying to evaluate wind damage for an insurance claim, or planning asset placement based on typical wind speed and direction, a weather data service such as Visual Crossing Weather provides wind data quickly and easily using global historical reports going back to 1970.
Wind data is typically composed of three values, and they are Wind Speed, Wind Direction, and Wind Gust. In the case of an hourly weather record, the wind speed measure reports the average wind speed over the past two-minute time window immediately before the report. In the case of a daily weather record, wind speed reports the maximum of those hourly records throughout the day. Wind direction is closely related to wind speed. Wind direction reports the average direction of the wind during the wind speed reports.
The third option to obtain wind data is to run a query via the Visual Crossing Weather API. Using an API allows you to run your query from inside any script or code automatically. The Visual Crossing Weather API uses a simple query URL to define a weather query. You can run this URL in a command-line tool such cURL, in your own script or code, or even directly in a web browser. The query returns the weather results including wind data in CSV or JSON format. CSV results are easily loaded into a database or data science tool while JSON is a format that is easily parsed in languages such as Python and Java. If you follow our how-to guide, you can learn how to run your first weather API query in just a few minutes.
Wind is an historical weather measure that is useful for many purposes including insurance, event planning, and asset management. Using Visual Crossing Weather, it is easy to find historical wind data for any worldwide location in several convenient ways. From the free Historical Weather Dashboard, to the weather query page, to a fully embeddable weather API for your code, Visual Crossing weather makes finding wind data simple.
Has anyone figured out the correct incantation of request parameters to get historic hourly weather conditions from WeatherKit? I've tried every combo of hourlyStart, dailyStart, currentAsOf, etc with past dates and it seems like the oldest it will go back to is midnight for today. I would like to get the last 24 hours of conditions.
With the Darksky API, it was possible to get hourly historical weather data of 50 years back. I am struggling with getting the same from the Weatherkit API. Is there an example call that provide e.g. the historical hourly weather data on a specific location, and a date of e.g. 20 years back?
The IEM maintains an ever growing archive of automated airport weatherobservations from around the world! These observations are typically called 'ASOS' or sometimes 'AWOS' sensors. A more generic term may be METAR data, which is a term that describes the format the data is transmitted as. If you don't get data for a request, please feel free to contact us for help. The IEM also has a oneminute interval dataset for US ASOS (2000-) and Iowa AWOS (1995-2011) sites. This archivesimply provides the as-is collection of historical observations, very little quality control is done. More details on this dataset arehere.
Provides access to all archived daily fire weather records for NFDRS stations in the United States, both manual and automated. It also is the source of fire occurrence data for all federal agencies and some state agencies. These files are formatted for easy import into FireFamily Plus. Updated annually.
Provides hourly data as well. Enter a WIMS ID into this application to quickly export all hourly records dating back to when the solar radiation sensor was installed on that station. Updated monthly.
Provides an archive to all Satellite (GOES) enabled RAWS stations. It is the most complete archive of hourly observations for the RAWS network. The interface provides many display alternatives (wind rose, summary tables, frequency distributions, and station metadata). The data lister provides for data download of archived data with a user password. Updated hourly.
Provides access to hourly data for a wide variety of weather stations across the United States. Outputs include map displays, tables, and graphs. For users that want to download quantities of data, consider Mesonet API where both ad-hoc queries and programmable requests can be formatted. Updated hourly.
Consider these steps when creating a FireFamily Plus database for your analysis area. You will want hourly data if you intend to use NFDRS 2016 fuel models, components, and indices. And this order will ensure that you get data with updated snowflag inputs.
Tides / Water Levels
The periodic rise and fall of a body of water resulting from gravitational interactions among the sun, moon, and earth. The vertical component of the particulate motion of a tidal wave. Users can retrieve data from active or historic stations. Water Level Landing Page Water Levels The height of the level of water relative to a Datum. Most stations with water level sensors provide readings every six minutes. Some, such as the 1-minute water level stations, provide readings once a minute. CO-OPS measures water levels at coastal stations and at many stations located around the Great Lakes. For coastal stations, water levels have a periodic rise and fall resulting from gravitational interactions among the sun, moon, and earth. For Great Lakes stations, changes in water level are usually due to weather events. 1-minute Water Level Data CO-OPS provides real-time access to 1-minute water level data to support tsunami detection, warning, and modeling, and support warning and mitigation of other coastal hazards. Data can be viewed numerically or graphically. NOAA Tide Predictions A calculation of what the water level will be based on harmonic constituents (see below). This site offers six-minute and hourly tide/water level predictions "on-the-fly" for all stations with harmonic constituents. It also offers high/low data for all stations in NOAA's published tide and current table. The site is updated every quarter; during the first two weeks of January, April, July and October. The quarterly updates may include the addition of new stations, updating subordinate and harmonic stations, and removal of superseded stations. Harmonic Constituents One of the harmonic elements in a mathematical expression for the tide-producing force and in corresponding formulas for the tide or tidal current. Each constituent represents a periodic change or variation in the relative positions of the earth, moon, and sun. A single constituent is usually written in the form y = A cos (at + "), in which y is a function of time as expressed by the symbol t and is reckoned from a specific origin. The coefficient A is called the amplitude of the constituent and is a measure of its relative importance. The angle (at + ") changes uniformly and its value at any time is called the phase of the constituent. The speed of the constituent is the rate of change in its phase and is represented by the symbol "a" in the formula. The quantity is the phase of the constituent at the initial instant from which the time is reckoned. The period of the constituent is the time required for the phase to change through 360 and is the cycle of the astronomical condition represented by the constituent. Datums For marine applications, a base elevation used as a reference from which to reckon heights or depths. It is called a tidal datum when defined in terms of a certain phase of the tide. Tidal datums are local datums and should not be extended into areas that have differing hydrographic characteristics without substantiating measurements. In order that they may be recovered when needed, such datums are referenced to fixed points known as benchmarks. The "Present Epoch" is from 1983-2001 and includes the latest datums available. The "Superseded Epoch" is from 1960-1978 and has been replaced by the "Present" datums, or was not replaced due to insufficient data. Bench Mark Data Sheets A fixed physical object or mark used as reference for a horizontal or vertical datum. A tidal bench mark is one near a tide station to which the tide staff and tidal datums are referred. A primary bench mark is the principal mark of a group of tidal bench marks to which the tide staff and tidal datums are referred. The standard tidal bench mark of the National Ocean Service is a brass, bronze, or aluminum alloy disk 3 1/2 inches in diameter containing the inscription NATIONAL OCEAN SERVICE together with other individual identifying information. The "Present Epoch" is from 1983-2001 and is the latest bench mark sheet available. The "Superseded Epoch" is from 1960-1978 and has been replaced by a "Present" sheet or was not replaced due to insufficient data. Sea Level Trends The rate of mean sea level rise or fall has been determined for 117 long-term water level stations. Monthly mean sea level data were used to obtain the linear trend, the average seasonal cycle, and the interannual variations. The linear trend at a coastal location is primarily a combination of the global sea-level rise and any local vertical land movement. The seasonal cycle and interannual variations are caused by fluctuations in coastal ocean temperatures, salinities, winds, atmospheric pressures, and currents. The interannual variations for many Pacific stations are closely related to the El Nino/Southern Oscillation. Assuming no change in trend, the time series of interannual variations are extended up to the latest month, and maps are created to show the regional extent of anomalously high or low water levels.
Sea Level Trends are available for both coastal and global stations. Extreme Water Levels Exceedance Probability Statistics on Extreme Water Levels now available for select water level stations in California, Oregon, Washington, and the Pacific Islands. Reports Various water level reports in table and report format. Coastal Inundation Dashboard Provides real-time and historical coastal flood information at a majority of active water level stations. Post-Event Peak Water Levels Peak water level observations from NOS stations during tropical storms, hurricanes and significant non-tropical coastal storms. Publications CO-OPS Publications The publications section is an extensive collection of CO-OPS recent and historic publications, including informational pamphlets, technical reports, technical memorandums, manuals and standards publications, storm reports, historical data reports and other popular publications. Most of the publications are available via PDF, others are described by an abstract and information on how to obtain them. CO-OPS Field Library The CO-OPS Field Library is a public document repository for manuals, standard operating procedures, publications and other documents and is maintained by the Center for Operational Oceanographic Products and Services (CO-OPS). Documents may be searched using title, author, and keyword/tags and can be downloaded using the filename link. Historic Tide and Tidal Current Tables NOAA's National Ocean Services (NOS) and predecessor offices have been annually publishing tide and tidal current predictions in hard-copy format, entitled "Tide Tables" and "Tidal Current Tables", since the 1860's. Electronic copies of the published "Tide Tables" and "Tidal Current Tables" from past year, as PDF documents, are made available through this page of the Tides & Currents website. Additional historic publications of the "Tide Tables" and "Tidal Current Tables" will be made available when they are converted to an electronic format. Currents Current's Landing Page Currents Generally, a horizontal movement of water. Currents may be classified as tidal and nontidal. Tidal currents are caused by gravitational interactions among the sun, moon, and earth and are part of the same general movement of the sea that is manifested in the vertical rise and fall, called tide. Tidal currents are periodic, with a net velocity of zero over the particular tidal cycle. See tidalwave. Nontidal currents include the permanent currents in the general circulatory systems of the sea, as well as temporary currents arising from more pronounced meteorological variability. Historic Current Data Each year, CO-OPS measures currents at many coastal locations in order to provide accurate tidal current predictions for the maritime community. These data sets typically range from one to three months in length and at most locations, data are available throughout the water column. This page contains the raw current measurements taken during these surveys, which date back to 1997.
