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.
