Environmental Layers for Europe?

[WolfeMD]

Hi all,

Would anyone be willing to share environmental layers for europe? Any
variable with a resolution of at least 1 km (30 arcseconds) or better
would be of great interest. In particular datasets for
evapotransipration, NDVI (and other vegetation indices) would be
awesome.

I've been looking for these data for some time now and while I see
them referenced and I'm sure they exist, I cannot seem to find the
dataset for download.

Thanks for the help,

Marnin

Dear Marnin
Have you looked at the global GIMMS NDVI (Global Land Cover Facility
http://glcf.umiacs.umd.edu/data/gimms/) and LAI layers (Boston
University http://cybele.bu.edu/modismisr/products/avhrrlaifpar.html)?
The LAI layers are available at 1km resolution, not sure about the NDVI
layers though. You can also look at the QSCAT (Quick Scatterometer)
which describes surface or canopy roughness, moisture, and other
seasonal attributes, such as phenological changes (see Long et al.,
2001). The GLOBCOVER global forestcover layer from 2004-2006 at
http://ionia1.esrin.esa.int/ I think also has a 1km resolution.

Hope this helps!
Jessi

He Jessica,

Thank's for the suggestions. GIMMS is only available in 8 km resolution, which I don't understand because it was derived from the MODIS satellite which says it records data in 1 km. The Boston University datasets don't seem to be either.  The link you sent for them didn't work and what I found via google didn't either.

I searched for the QSCAT data you mentioned. All I found was that it is wind speed data at a 25 km resolution.

I found this: https://lpdaac.usgs.gov/lpdaac/products/modis_products_table (also see: https://lpdaac.usgs.gov/lpdaac/products/modis_products_table/vegetation_indices/16_day_l3_global_1km/v5/terra).

The datasets are available straight from NASA/USGS satellites. They are free. The catch? The data-access system is so unorganized and difficult to work with I have so far failed to find what I am looking for. Anyone had success with this beast of a resource? 

Cheers,

Marnin

Hi Martin,
The Boston Univ. datasets are at <http://cybele.bu.edu/modismisr/>,
there you can open a ftp session at the <LAI & FPAR Products!> link.

Information on QuikSCAT datasets generated (if I am not wrong) by Sasan
Saatchi are available at
<http://www-radar.jpl.nasa.gov/carbon/rs_ab.htm>, click on "Project Web
Site" and in the left panel of the new page, on Remote Sensing Data. You
will see several datasets, one of them "QSCAT Time Series". Click there
and you will land in another page with "QSCAT Monthly Mean" which will
take you to <ftp://www-radar.jpl.nasa.gov/projects/carbon/ab/QSCAT/>,
although those .byt are only for part of South America. In a separate
mail I am sending to you three pertinent papers you definitely must read
if you plan to use this kind of data (if somebody explains to me how to
upload them to the Maxent site I'll put them there; I'm a member, but I
don't see any way to upload them; sorry for my ignorance).
If you need other area you have to download raw images in .sir format.
You must go to <http://search.scp.byu.edu/> and search for you area. You
will download the .sir images and translate to grids. It is not for the
faint hearted, I warn you... In this page
<http://www.scp.byu.edu/FAQ.html> you can find the way to get some light
from the darkness...
The ftp (I can send you the script I wrote to download all the South
America and you can modify it according to your needs) is very effient,
and then you can massively translate those .sir to ESRI grids using the
Marine Geospatial Ecology Tools <http://code.env.duke.edu/projects/mget>.

Prepare some coffee, and be patient... you need some expertise on
ArcInfo (to automatize the whole thing) or ArcGIS.
