Trim size of CSPP SDR for use in Docker

Post by sverrem »

Is it possible to trim down the size of the CSPP SDR to process VIIRS?
Creating a docker image with the SDR software (without the ancillary and luts) makes the docker image almost 6GB in size.
The SDR v3.2 took 4.22GB, while the latest v3.3 takes 5.77GB in docker image size.

The ancillary and luts are provided during startup of the docker image, since these take up approx 60GB.
Is there anything else we can remove from the SDR directory that is not needed to run VIIRS processing?

Dear Colleague,

The SDR software is trimmed as much as possible. We cannot think of any easy way to make the core software a smaller size. In fact, in the future, this size is very likely to grow since support for a third JPSS satellite (NOAA-21) will be added in the next CSPP SDR software release.

Sorry I cannot be of more help.

There are 3 software packages in CSPP SDR: VIIRS, ATMS and CRIS

Currently we are only using the SDR for processing NPP/NOAA VIIRS.
Unfortunately there is not much to save for these directories
24K atms
24K omps
48K cris
68K viirs
3,7G common

Most of the size resides in the common directory. Where the majority of storage resided within 3 directories
785M ADL
866M local
2,1G ShellB3

Hi,

SDR is packaged and tested to work with all three instruments. Removing parts of the package invalidates the testing so it is not recommended. Is there a specific reason that the additional size of the software package is causing a problem? In addition to producing VIIRS SDRs are you creating quick-looks? Do you plan on adding more instruments in the future?
