  1. Status/Update on MiRS for FY3-MWRI Tiger Wanchun Kelvin Sid 04/17/2009

  2. Contents • 1. calibration coefficients in MWRI L1 Tb datasets were updated by using the cross-calibration results with windsat; • 2. run MiRS to get all of the results by using the new datasets • 3. progress in IR-MiRS

  3. Bias histogram of mwri-windsat 10-36GHz and mwri-F15-ssmi at 89GHz

  4. Comparison between mwri measurement and model simulation from 10-89GHz

  5. Update to MiRS • 1.updated the bias correction file and model bias correction data file under semistatic data directory; • 2.modify the griddata program, discard the ascending / descending node justification in program code; • 3.all changes has submitted to wanchun and checked in, make sure it is consistant with repository.

  6. Qc fail area

  7. IR hyper-spectrum SVD analysis • Datasets: • Source: GFS VI~IR spectrum datasets • Spectrum range: 0.40 ~ 14 µm • Spectrum resolution: 0.01µm • Surface type: • 1: broadleaf evergreen tree (tropical forest) • 2: broadleaf deciduous tree (mid-latitude forest) • 3: broadleaf & needleleaf tree (mixed forest) • 4: needleleaf evergreen tree (high-latitude pine forest) • 5: needleleaf deciduous tree (high-lat pine forest, Siberia only) • 6: broadleaf tree with groundcover (savanna) • 7: groundcover (grassland) • 8: broadleaf shrub with perennial groundcover (desert, dry grassland) • 9: broadleaf shrub with bare soil (desert) • 10: dwarf tree and shrub with groundcover (tundra) • 11: bare soil (desert) • 12: cultivations (agricultural land) • 13: glacial-ice (Greenland/Antarctica ice sheet only) • Analysis method • 1.SVD (singular value decomposition ) • 2.PCs composition test

  8. Comparison of first 3 PCs Comparison of PCs composite spectrum and raw spectrum

  9. Future work • Validation of MWRI TPW products by using radio-sonder data (from Raob); • HIRS simulation by using CRTM under MiRS frame
