• K. Garrett, F. Iturbide-Sanchez, C. Grassotti,
  and W. Chen

2
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

3
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)

4
MiRS Status (2/3)
NPP Sample ATMS TDRs (from IPO)
Resampled Metop-A AMSU/MHS to ATMS
frequency/geometry (code from MIT LL)
5
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

6
Review Aspects

• We will review performances of products that are
  part of this release
• Package, New features of Web site

7
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.

8

• Review of NOAA-19

9
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.
