Hello Alejandro, I do not know what is causing the failure of your sdr_luts.sh scripts. To help us investigate the cause, can you please try executing the script again using the "-v" option, and sending us the log results? For instance: sdr_luts.sh -v sdrluts_output.txt 2>&1 and send u...

Hello Alejandro. I hope that you are well. I can answer your question about the AIT failure and the log that shows ancillary data downloads failing. We have experienced an ancillary data outage starting late yesterday afternoon (15 April). I have just finished getting the files up to date. Please ch...

Hello Margad, There are programs that can read and write data files and save them as different formats. For example, the gdal command gdal_tranlsate can do this. You can find this and other utilities at https://gdal.org. The next release of Polar2Grid (Version 3.1) will support VIIRS Land Surface Re...

Update #4 Issued April 04, 2024 1604Z: On April 4th, 2024, the NOAA-20 propulsive maneuver was executed successfully with a verified burn that was an expended delta-v duration of 299.2 thruster seconds on 11:56:00Z-11:57:50Z to complete the rephasing campaign. 12:08:13z OMPS returned to fully opera...

Hello, The short answer then is that there is no convenient way to get older ancillary data from from geodb website. Some of the GEOCAT ancillary datasets are standard, and some are unique to the product. For example, the snow_map product is one that was created from other ancillary specifically in ...

Update #3: Issued April 02, 2024 1622Z On April 04, 2024 11:56:00Z, NOAA-20 will perform a 110 second propulsive Re-Phasing Maneuver (RPH) to re-establish mission orbit.

Hello again Margad, > 1. Could you please advise on the process of obtaining Surface Reflectance (Bottom of Atmosphere reflectance) from SDR data? The SDRs do not contain surface reflectances. They contain observed radiances at the satellite sensor above the atmosphere, which are then also converted...

It has come to my attention that the last 2 parameters listed for the ABI 500m grid are off by 1/2 the width of a pixel, i.e., 250m. The config file lists the following values:

-5434894.885056, 5434894.885056

I believe these values should instead be:

-5434644.885056, 5434644.885056
