List of Scientific Changes:
• Cloud Mask: New snow modification routine. New cloud mask mode added.
Updated to mode 2 with new LUTs and code logic.
• Cloud Phase: New cloud phase science version.
• Cloud Height: Update for opaque cloud temperatures. Science update to improve matrix and convergence calculations by using kdtree machine learning.
• DCOMP: Science code update for visible reflectance and thick clouds. Added snow modification routine. New NOAA-21 LUTs. Added a new Nighttime Lunar COMP module to calculate microphysical properties during nighttime granules and when lunar reflectances are valid (moon is shining over the surface). Changed max solar zenith from 75 to 82.
• Cloud Base: Science update to improve nighttime arctic retrievals.
• New Product: Cloud Cover Layers: Added Cloud Base as a dependency. Added DQF.
Added capability for Convective Cloud Probability & Supercooled Water at 5 flight layers. The PDA short name is JRR_CloudCoverLayers.
• ADP: Science update and minor bug fix. Added J2 support, updated coefficients in algorithm configuration. Added fix required because of changes to the cloud mask packed flag.
• AOD: Science update. Fixed initialization and pointers. Changed to use 17 classes of Surface Type rather than 14 class Surface Type.
• Ice Concentration: Created a reader and interpolated the 10km input data (on EASE-2 grid) to satellite grid. Used to screen out regions of low ice concentration at night.
• Ice Age: Science update. Added check for solar zenith angle between 85 and 93 degrees
• Snow Cover: The stripping in NOAA-20 VIIRS Snow product has been properly indicated in the QCs
CrIS BUFR Products: The cloud information included in the CrIS BUFR products will reflect the JPSS Risk Reduction (JRR) updates.
VIIRS Polar Winds: The polar winds products will reflect the JRR updates.

List of Scientific Changes:
1) Added J02 (NOAA-21) processing capability.
2) Updates to the snowfall rate (SFR) algorithm software including
● final version is ready for J02 processing
● machine learning based snowfall detection algorithms for SNPP and NOAA-20
● new radiometric bias corrections for SNPP and NOAA-20
● cloud temperature initialization for SNPP and NOAA-20
● machine learning based ice water path initialization for SNPP and NOAA-20 over CONUS
● machine learning based SFR bias correction for SNPP and NOAA-20 over CONUS
3) Integration of an additional option for the radiometric bias correction for S-NPP and NOAA-20. The new option is a dynamic bias correction which uses a machine learning approach to compute a unique bias correction for each individual scene based on its radiometric and geophysical characteristics. The default option remains as before, the use of a static bias correction. Selection of the bias correction option is determined in the static tuning files located under data/StaticData/TuningData. Separate tuning files with flags set to use the machine learning correction are contained in the package and can be used by simply modifying the PCF to point to these files. (Note: prior to recommending this option for operations, the science team will brief stakeholders at a future date on comparative results to make sure there is consensus on switching to the new option).
4) Added one new parameter ‘char quality_information’
5) Added one new attribute ‘ascend_descend_data_flag ’ in the global metadata
6) Made the global attributes better compliance with NDE guidelines and CF conventions

List of Scientific Changes:
• Since 2017 NVPS VI has been developed in multiple versions. The NVPS VI-v1r4 version is operationally producing VIs in NOAA using SNPP and NOAA-20 observations as of July 2020. However, there exist three drawbacks in this operational NVPS VI version: operational time over 7 hours, quality flags of VIs only with two ranks (good or poor), and, unreasonable sun zenith angle and view zenith angle at some aggregated grids.
• The updated NVPS VI DAP v2r1 aims to overcome the above-mentioned drawbacks through redesigning some spatial aggregation and temporal compositing algorithms and improving their implementation. (For detailed descriptions and flowcharts refer to these documents: VIIRS VI ATBD version 2.0, VIIRS VI EUM, and VIIRS VI SMM.)
• Testing showed that the updated NVPS VI reduced operation time from the original 7+ hours to 3 hours. In addition, the new version produces redesigned quality flags with 13 ranks that describe, in more detail, quality properties of VI products.
• The new version also produces more reasonable view angles than the previous version.
• Input for GVF is now IP from the VI process. GVF will need VI-SR files from the VI process.

List of Scientific Changes:
• Snow/Snow-free observations separation in offline temporal filtering
• Mark snow/snow-free flags for each L2 albedo layers within the filtering window
• Use snow (snow-free) only observations in temporal filtering for snow (snow-free) pixels in the current day
• If there is no historical snow (snow-free) observations when the current day is snow (snow-free), use all valid observations within the filtering window to do temporal filtering, which is the same as the original algorithm
• Climatology updated to version 5 with upgraded quality
• Files now stored in netCDF format instead of binary .img files
There is no change for LSE.

List of Scientific Changes:
• The gridded LSA code now have to read in that NetCDF instead of the binary intermediate;
• The gridded LSA product now uses a new "tilelist.txt" which slightly changes which tiles are used, but the impact is really minor.
• The gridded LST code now have to read in that NetCDF instead of the binary intermediate;
• The gridded LST puts out a new dataset "View_Angle" which appears to be the viewing zenith angle of the satellite.
