I have a .UF file with the wrong latitude and longitude

[Eliton lima de figueiredo]

Dear Py-ART users,

I have a .UF file with the wrong latitude and longitude (-28 775, -53.07) for the radar location. I have with the correct coordinates (-29, -54).
I have an attached figure showing the correction that I want to perform.

I would also like to correct or change the background map because it does not show the desired  political map.

sincerely

link UF file:
http://200.132.99.1/prev/temp/2014-10-19--03_20_23_00.mvol.UF

import numpy as np
import matplotlib.pyplot as plt
import pyart

# read in the file, create a RadarMapDisplay object
filename = '2014-10-19--03_20_23_00.mvol.UF'
radar = pyart.io.read(filename)
display = pyart.graph.RadarMapDisplay(radar)

# plot the second tilt
display.plot_ppi_map('corrected_reflectivity', 1, vmin=0, vmax=65,
                     min_lon=-65, max_lon=-45, min_lat=-40, max_lat=-23,
                     lon_lines=np.arange(-65, -45, 5),
                     lat_lines=np.arange(-40, -23, 5), resolution='h',
                     cmap='pyart_NWSRef')
plt.show()

Hey Elton,
First: nice data!

Second: you can edit the lat/lon yourself..

radar.latitude['data'] = np.array([mylat])
radar.longitude['data'] = np.array([mylon])

so:

import numpy as np
import matplotlib.pyplot as plt
import pyart

# read in the file, create a RadarMapDisplay object
filename = '2014-10-19--03_20_23_00.mvol.UF'
radar = pyart.io.read(filename)

radar.latitude['data'] = np.array([-29])
radar.longitude['data'] = np.array([-54])

display = pyart.graph.RadarMapDisplay(radar)

# plot the second tilt
display.plot_ppi_map('corrected_reflectivity', 1, vmin=0, vmax=65,
                     min_lon=-65, max_lon=-45, min_lat=-40, max_lat=-23,
                     lon_lines=np.arange(-65, -45, 5),
                     lat_lines=np.arange(-40, -23, 5), resolution='h',
                     cmap='pyart_NWSRef')
plt.show()

worked, thank you very much for your help.

Dear All,

I am trying to open a .mvol radar file using the function "read_gamic", but it is not working. I get several error messages. Is it possible to open a .mov file using "read_gamic"? If not, what alternative do I have?

Thanks in advance.

filename = '2014-10-19--03_20_23_00.mvol'
radar = pyart.aux_io.read_gamic(filename)

Hi,

I opened an issue here https://github.com/ARM-DOE/pyart/issues/534.

An alternative would be to just open the mvol with an hdf5-reader (it's
actually an hdf5) and extract the needed data for adding to a
radar-object. I'm short of ideas if this is possible out of the box with
pyart, but surely Jonathan has some.

If this is really urgent, you might try wradlib-functions to read the
data and then import it into an pyart radar object or just visualize it.

Cheers,
Kai

Hi,

I have a PR here which solves the reading problem of the OP as a first
step (https://github.com/ARM-DOE/pyart/pull/535).

The attached synthetic RHI is produced from the read radar-object.

Cheers,
Kai
