NUCAPS EDRs (Environmental Data Records) are now populating space in the cloud, such as at this Amazon webservices (AWS) link https:\/\/noaa-nesdis-n20-pds.s3.amazonaws.com\/index.html<\/a>. This is part of the NODD<\/a> (NOAA Open-Data Dessemination) project. At that AWS link you will see a ‘NUCAPS-EDR’ directory, and dropping down through year\/month\/day selections, a list of filenames appears with names such as: NUCAPS-EDR_v3r1_j01_s202405141514589_e202405141515287_c202405141606240.nc<\/code><\/a> ; ‘j01’ identifies the satellite as NOAA-20; data in this file starts 15:14:58.9 on 14 May 2024, ends at 15:15:28.7 on 14 May 2024, and was created on 16:06:24.0 on 14 May 2024. The file listing shown below as a screen-capture shows data from 1725 to 1732 UTC on 14 May 2024.<\/p>\n\n\n\n

These data can be displayed most easily by knowing when NOAA-20 overflew a region, and this website<\/a> helps with that. The GOES-East projection showing NOAA-20 orbits on 14 May is shown below. Focus on the ascending pass off the East Coast of the United States, from 17:25 to 17:32 or so.<\/p>\n\n\n\n

After downloading the Sounder QuickLooks software<\/a> (from CSPP<\/a>), 7 commands created the mapping of temperature shown up top. First, the .qz file that includes the software packages was expanded and I changed locations to the created directory, making that the home directory with the export command. A shell script within the directory is then sourced to set up environments (one result of this shell script is that the $CSPP_SOUNDER_QL_HOME\/bin directory is added to a user’s $PATH). Then I changed to the bin directory. The script ‘getall’ retrieves the netcdf files from the cloud — it’s a series of unix wget commands, i.e., “wget https:\/\/noaa-nesdis-n20-pds.s3.amazonaws.com\/NUCAPS-EDR\/2024\/05\/14\/NUCAPS-EDR_v3r1_j01_s202405141725389_e202405141726087_c202405141803060.nc\".<\/code> The variable ‘files’ matches all of the netcdf files that were downloaded. Finally, the 700-mb temperature field is created, as shown above. (Note: because the cspp_sounder_ql_env shell script puts the bin directory in the user’s $PATH, the ql_level2_image shell script below could be invoked from any directory. In other words, there’s no need to put the netcdf files in the bin directory!)<\/p>\n\n\n\n
