IPOPP v4.0 Patch 1 Released - 12/4/2020

In response to the recent science team announcement for MODIS and OMPS data outage, the DRL is pleased to announce the expedited release of IPOPP v4.0 Patch 1. This patch updates the de200.eos file in relevant SPAs within your system; a table critical for science processing that expired one month early on December 1.  We strongly recommend that you apply Patch 1 to your IPOPP v4.0 installation immediately.
You may reprocess impacted data products using the IPOPP Pass Manager in order to continue your record since this data outage began.  Please refer to Appendix G of the IPOPP v4.0 User Guide for details.  The Pass Manager facilitates the reprocessing of SNPP/JPSS RDR and PDS files as well as Terra/Aqua/SNPP/JPSS PDS (packet file and CSR) file pairs corresponding to a satellite overpass, resulting in the regeneration of all downstream science data products associated with the overpass.
Note: I remind there is and has been no support for standalone SPAs for some time.

OMPSNADIR SPA v2.6.9 Released - 1/20/2020

The DRL is pleased to announce the release of OMPSNADIR SPA v2.6.9.  The Ozone Mapping and Profiler Suite (OMPS) nadir Science Processing Algorithm (OMPSNADIR_SPA) processes SNPP OMPS Level 0 Production Data Production Data Set (PDS) files into Level 1A, Level 1B and Level 2 data products.  This SPA functions as an IPOPP plug-in (IPOPP v4.0 required).  For updating OMPSNADIR from v2.6.7 to v2.6.9, simply follow the instructions in the IPOPP User Guide for  a seamless update of this SPA into your operational environment.
Enhancements to v2.6.9 include:
  • improved sensitivity to reduce false detections;
  • improved twilight pass processing to eliminate errors by downstream algorithms within IPOPP.
The OMPS PDS inputs may be created with the DRL's Real-time Software Telemetry Processing System (RT-STPS), v6.0 or later, available here.  
The OMPSnadir algorithm was provided to the DRL by the Ozone Science Investigator-led Processing System (SIPS) Team.  We appreciate our colleagues’ contributions from the Finnish Meteorological Institute (FMI, SAMPO Team) and the Geographic Information Network of Alaska (GINA)!

The following data format details exist within the OMPSNADIR v2.6.9 User Guide but are provided here for informational purposes.
The OMPSnadir algorithm takes as input eight files in PDS format:
  • APID 0008 construction record (filename P1570008*0.PDS);
  • APID 0011 construction record (filename P1570011*0.PDS);
  • APID 0008 packet (filename P1570008*1.PDS);
  • APID 0011 packet (filename P1570011*1.PDS);
  • APID 0560 construction record (filename P1570560*0.PDS);
  • APID 0561 construction record (filename P1570561*0.PDS);
  • APID 0560 packet (filename P1570560*1.PDS);
  • APID 0561 packet (filename P1570561*1.PDS).
The OMPSnadir algorithm also requires leapsec and utcpole ancillary data files as input. It creates nine output products:
  • OMPS Total Column Level 1A EV;
  • OMPS Total Column Level 1B EV;
  • OMPS Total Column Total Ozone;
  • OMPS Total Column Total SO2 Near Real-time;
  • OMPS Nadir Profile Level 1A EV;
  • OMPS Nadir Profile Level 1B EV;
  • PNG image for Ozone;
  • PNG image for Reflectivity at 331nm;
  • PNG image for Ultraviolet Aerosol.


IMAPP SPA v3.1.1 Patch 2 Released - 1/8/2020

The DRL is pleased to announce the release of the IMAPP v3.1.1 Patch 2.  This patch addresses a date handling issue in the core algorithm that prevented the IMAPP v3.1.1 from emitting output beginning on January 1, 2020.  The contributions of users in identifying and resolving this matter are greatly appreciated!
The Science Processing Algorithm (SPA) implementation of select NASA Level 2 algorithms from within the International MODIS/AIRS Processing Package (IMAPP) was created for real-time or near real-time applications within the multi-mission, multi-discipline International Planetary Observation Processing Package (IPOPP) framework. The IMAPP SPA v3.1.1 consists of official NASA algorithms only, and processes MODIS Aqua and Terra Level 1B data into the following MODIS Level 2 atmospheric products:
  • Cloudmask (MOD35);
  • Cloudtop Properties, Cloud Phase and Cloud Optical properties (MOD06);
  • Atmospheric Profiles (MOD07);
  • Aerosol (MOD04); and
  • Aerosol 3km.
