Update #5 - JPSS J01 SMD Data Delay - Issued: February 06, 2024 2208Z Update #5: VIIRS Cal/Val team is reporting a significant issue: longwave channels (M14-M16, I5), data quality flags at pixel level (QF1) are erroneous (labeled as poor qualify for good data). As a result, the VIIRS SDR team recom...

Hello Margad, 1.) To create a 375 m spatial resolution image, you will need to create your own grid. The easiest way to do this is by using the p2g_grid_helper.sh script. You can find instructions on how to use this script in the Polar2Grid documentation, online at : https://www.ssec.wisc.edu/softwa...

Hello again Andrew, Sorry that we have not gotten back to you before now. We considered the best way to advise you in using legacy LUTs with the VIIRS CSPP SDR software, and we found that there really is no easy way to do this. It is possible to provide a date to `sdr_luts.sh -t `, which will downlo...

Hello, The data that you downloaded from NOAA CLASS is not SDR data, it is the NOAA Imagery EDR. Polar2Grid does not support that product. The CLASS menu option to choose is "JPSS VIIRS SDR Operational (VIIRS_SDR). If you choose "De-aggregate JPSS Data Products" under the CLASS "...

Hello, Polar2Grid is not supported on Windows Operating Systems. However, we have tested parts of Polar2Grid Version 3.0 on Windows Subsystem for Linux (WSL) Ubuntu. As the documentation says "Windows Subsystem for Linux (WSL) is a feature of Windows that allows you to run a Linux environment o...

We do have it Andrew, and will send you the instructions.

Cheers,

Kathy

Okay Andrew, I think I understand. I am not sure that the CSPP software is the best one to use for your investigation. The main use case for this work is supporting the near-real-time direct broadcast community which means things like we provide only one "VIIRS-RSBAUTOCAL-HISTORY-AUX" LUT ...

Hello Andrew, Can you tell me which LUTs you are interested in? This process is complicated by: 1). Often times the LUTs are not compatible between different versions of ADL. That is why we have new LUT download https sites for new CSPP versions. We are on LUT site number 6 now. In the CSPP Installa...

Hello Andrew, The ancillary data for the days that you requested have been staged at the online archive. I recommend executing the GEOCAT software for these dates as soon as possible, as the ancillary files will be automatically scrubbed after a couple of days. Please let us know if you need any oth...
