29th Operational-MIRS Meeting
June 12th 2009K. Garrett, F. Iturbide-Sanchez, C. Grassotti, and W. Chen
Agenda
• Status & Overview of the 6th release of MiRS [Kevin]• MiRS Operational Status [OSDPD]• Review of N19 MiRS performances [Kevin]• Review of F16 MiRS rainfall rate performances [Flavio]• Review of MiRS Package/System/Web-site [Wanchun]• Discussions [All]
MiRS Status (1/3)
• Extension of MiRS to ATMS (NDE integration)– Received updated ATMS sample data from
IPO, as well as resampling code from MIT Lincoln Lab (Matlab)
– Resampled SDRs will be helpful (development, daily processing)
– The usual steps for extension of MIRS to a new sensor (bias correction, emissivity covariance matrix)
MiRS Status (2/3)NPP Sample ATMS TDRs (from IPO)
Resampled Metop-A AMSU/MHS to ATMS frequency/geometry (code from MIT LL)
MiRS Status (3/3)
• In the works (but not for the 6th release)– Improvements to sounding (investigating Sfc
P impact both in retrieval and bias correction computation)
– Improvements to the rainfall rate. Training on multiple data sources (TRMM, MM5 etc)
– Experimental retrieval of wind speed over ocean from emissivity catalogs
Review Aspects
• We will review performances of products that are part of this release
• Package, New features of Web site
MiRS 6th Release to OSDPD
• MiRS DAP package to be delivered to OSDPD on June 15th.
• Package tested daily on all sensors on the STAR machines (Linux).
• Package tested on OSDPD IBM machines as well (orbital mode).
• First official delivery with NOAA-19 processing capability.
• F16 SSMI/S hydrometeor profiles/rainfall rate retrieval.
• Further validation/assessments of the rainfall rate.
Review of NOAA-19
Review of NOAA-19
• NOAA-19 processing capability part of delta-DAP delivered on March 23, 2009.
• Same product set as for NOAA-18.
• Similar performance relative to NWP, RAOB, TRMM, etc. as NOAA-18 for all products.
• No changes to MIRS components specific to NOAA-19 since delta-DAP release.
