NASA GRIB weather data

Dr. Hossain and I ZOOMed briefly today. Dr. Hossain said that GRIB is the new NASA standard, so we should use PYGRIB https://jswhit.github.io/pygrib/docs/. 

Dr. Hossain suggest this data set

The files for this data set are available as global rasters in GeoTIFF, ASCII (text), and netCDF format. The ASCII and GeoTIFF data are available at the native 30 arc-second resolution and four lower resolutions: 2.5 arc-minute, 15 arc-minute, 30 arc-minute, and 1 degree. NetCDF files are available at all resolutions except 30 arc-second. The data are stored in WGS84, geographic coordinate system (latitude/longitude).

Each downloadable is a compressed zip file containing either the global GeoTIFF or ASCII for the year and resolution of the estimate, or the netCDF containing all years of the estimate at a selected resolution, as well as data quality layers and ancillary files. A separate documentation zip file contains PDF documentation, a Microsoft Excel file (.xlsx) with country-level information and sources, and a text file (.txt) with a log of changes to the data set by version.

The netCDF file format is only available for the All Years Combined category and is not available at 30 arc-second

*** Air temperature NASA data

AIRS3SPD: AIRS/Aqua L3 Daily Support Product (AIRS-only) 1 degree x 1 degree V006

The Atmospheric Infrared Sounder (AIRS) is a grating spectrometer (R = 1200) aboard the second Earth Observing System (EOS) polar-orbiting platform, EOS Aqua. In combination with the Advanced Microwave Sounding Unit (AMSU) and the Humidity Sounder for Brazil (HSB), AIRS constitutes an innovative atmospheric sounding group of visible, infrared, and microwave sensors. The L3 support products are similar to the L3 standard products but contain fields which are not fully validated, or are inputs or intermediary values. Because no quality control information is available for some of these fields, values from failed retrievals may be included.
