Error with meteorological dataset download #258

Open simovir89 opened 5 months ago

simovir89 commented 5 months ago

I'm using Gis4wrf with QGIS version 3.28, lately I have a problem with the automatic download of meteorological data. I noticed that the authentication method has changed on the site https://rda.ucar.edu/. In this regard, I report the screenshot of the error and I would like to ask you if anyone is in the same situation as me.

Thank you. Screenshot_error

I have the same issue. It is not difficult download data from rda's page, but could be fairly straightforward from gis4wrf.

Hi, we are experiencing the same issue. I already tried to update the plugin to the latest version, and download the WPS and WRF mpi packeges but the error is still occurring. I tested the UCAR website and is up and running. Do you have any solutions? Thanks in advance

Hi mybad87,

Previously, to download UCAR weather data an account was required, which is what GIS4WRF asks for (configuration > option > gis4wrf > username & password). It is no longer necessary to have an account to download the data and GIS4WRF appears to have not been updated on this.

My solution was to download the data from the page (https://rda.ucar.edu/datasets/ds083.3/dataaccess/) and then: Data access > Web File Listing > Complete File List. Then, I downloaded the data with a csh code.

@SurAurora thanks for your reply! Yes, I was thinking about that, have to find a way to subset a request to limit the total amount of data to download. I'll try to go through the source code of the plugin to see which parameter are requested to form the grib file. Subsetting by a restricted area also would be useful to cull the grib data. Doing this to be sure AERMOD correctly reads the record preventing errors. Do you have any advice about a way to achive that?
