GeoDB OISST data

Hello, I was wondering if there were convenient ways to retrieve older ancillary data from the geodb website (https://geodb.ssec.wisc.edu/ancillary/) for processing. Are there good substitutes for files like the snow maps, or oisst data on NOAA PSL or CLASS? Or does the software conform to an intern...

Re: GEOCAT AHI resolution

Hi Jess,

Why is that? Are there future plans to change this, or implement options for user control?

Thanks,

GEOCAT AHI resolution

Hello, When processing GEOCAT HSD AHI data, I noticed that all bands shared the same resolution for L1 products and for L2 products. While native HSD AHI data contains a mix of spectral resolutions, 0.5km to 1km for visible, and 2 km for infrared. Is there any way to specify the output resolutions o...

Re: GEOCAT GEODB missing values

Hi Kathy,

We might use the full ancillary dataset later but for now it is not needed, much thanks again for the help. I'm currently affiliated with, and using the output for GEOIPS.

Thanks,
Andrew

Re: Offline usage of legacy LUTs

Hi Kathy,

That would be great, I would love some instructions/advice for how to properly look into this, do you need my email directly or do you have access to it?

Re: Offline usage of legacy LUTs

Hi Kathy, I'm primarily interested in the dynamic VIIRS LUTs for JPSS-02 , if I'm not mistaken this would be the DNB darks/flats (DN0), DNB Gain ratios, stray light corrections, and maybe a few other files. Is there a way to set which LUTs or range of dates for LUTs to use? I primarily use this to l...

Offline usage of legacy LUTs

Hello, I was wondering if there were options or a simple way to force the viirs_sdr script to utilize older LUT values for processing. I wanted to test different versions of the LUTs and see how calibration has changed overtime. I tried running VIIRS SDR processing in offline mode with older LUT val...

Re: GEOCAT GEODB missing values

Hi Kathy,

Thanks for the clarity, if you could populate the database with dates 2022-01-07 through 2022-01-12 that would be great. For now I don't need all the ancillary files, but I'll keep you updated just incase.


Thanks,
Andrew
