Topic: NDE System Upgrade

M-B

Date/Time Issued: August 21, 2019 2025 UTC

M-B

Product(s) or Data Impacted:M-B All NDE products

M-B

Date/Time of Initial Impact:M-B September 5, 2019 TBD UTC

M-B

Date/Time of Expected End: September 5, 2019 TBD UTC

M-B

Length of Outage: M-B 2.5 hours

M-B

Details/Specifics of Change:

Install NDE release 2.0.19

M-B

This installation is planned to be done during back orbits. NDE will not be ingesting, processing or distributing data during installation.M-B No data loss expected, but there will be a possible backlog of processing when installation is complete.

M-B

Algorithm changes are as follows:

M-B

1) NUCAPS low resolution products in NetCDF and BUFR formats:

M-B

The products will have IDPS generated VIIRS Cloud Mask and Cloud Height replaced with JPSSRR (JPSS Risk Reduction) generated Enterprise VIIRS Cloud Mask and Cloud Height.

M-B

Please note: Existing PDA subscriptions will not need to be changed because the file short names will remain the same.

The newly generated NetCDF4 and BUFR products have the following filenames and corresponding PDA product shortnames:

M-B

New (NUCAPS 4.3):

File name NUCAPS-C0399_v2r0_npp_s*.bufrM-B M-B M-B M-B Shortname CrIS_C0399_BUFR

File name NUCAPS-C1305_v2r0_npp_s*.bufrM-B M-B M-B M-B Shortname CrIS_C1305_BUFR

File name NUCAPS-ALL-LR_v2r0_npp_s*.ncM-B M-B M-B M-B Shortname NUCAPS_ALL

M-B

OLD (NUCAPS 3):

File name NUCAPS-C0399_v1r0_npp_s*.bufrM-B M-B M-B M-B Shortname CrIS_C0399_BUFR

File name NUCAPS-C1305_v1r0_npp_s*.bufrM-B M-B M-B M-B Shortname CrIS_C1305_BUFR

File name NUCAPS_ALL_?????????_*.ncM-B M-B M-B M-B M-B M-B Shortname NUCAPS_ALL

M-B

2) M-BNDE enterprise cloud, aerosol and cryosphere products (SNPP and NOAA-20)

M-B

NDE enterprise cloud, aerosol and cryosphere products upgrade from v2.0 to v2.1. Other than algorithm updates and bug fixes (details will be shared with users through email), cloud cover layers algorithm has been removed from cloud height and will be made available in the future upgrade as a separate product . Version number in the filename will be changed from v2r0 to v2r1. Product short name remains the same in PDA.M-B

M-B

Filename change example:

OLD:

JRR-CloudMask_v2r0_npp_s*_e*_c*.nc

JRR-CloudHeight_v2r0_npp_s*_e*_c*.nc

M-B

NEW:

JRR-CloudMask_v2r1_npp_s*_e*_c*.nc

JRR-CloudHeight_v2r1_npp_s*_e*_c*.nc

M-B

3) VIIRS Polar Winds (SNPP and NOAA-20)

M-B

This is a relatively minor update. The contents of metadata in the netcdf product file are corrected and updated.

M-B

4) VIIRS Land Surface Temperature and Albedo with NOAA-20 and SNPP

M-B

This implementation will produce Land Surface Temperature and Albedo from NOAA-20. The file name conventions will remain the same as those from current NPP except replacing satellite ID npp and version v1r0 with j01 and v1r2 as below,

M-B

LST_v1r2_j01_s*_e*_c*.nc

SURFALB_v1r2_j01_s*_e*_c*.nc

M-B

The file name for NPP is the following:

LST_v1r2_npp_s*_e*_c*.nc

SURFALB_v1r2_npp_s*_e*_c*.nc

M-B

5) VIIRS Green Vegetation Fraction/Vegetation Index (NOAA-20 and SNPP)

M-B

This update will fix an error from last installation, which will make sure intermediate products EVI will be derived from clear composite surface reflectance from the previous week vs just the previous day. VIIRS GVF/VI products quality may be negatively impacted from both S-NPP and NOAA-20 until this update is completed.M-B

M-B

Please note: This upgrade will not be performed during Critical Weather Day (CWD).M-BM-B

Additionally, the contents of this release are subject to change based on user readiness, customer feedback, and management approval.M-B Additional ESPC notifications will provide further details and updates concerning this release. User feedback and questions should be emailed to Shuang Qiu shuang.qiu@noaa.gov.
