Presentation Transcript

  1. OLYMPEX CFAD Analysis S. Brodzik et al. PMM Science Team Meeting, Houston, 25 October 2016 Supported by NASA grants NNX16AD75G, NNX15AL38

  2. NPOL East vs West NPOL vs GPM-Ku GPM Ka vs Ku

  3. NPOL West vs East East West

  4. NPOL East Minus West • Positive values clearly show orographic enhancement • Negative values show blockage to east

  5. NPOL vs GPM-Ku NPOL GPM-Ku

  6. GPM Ka vs Ku Band GPM-Ku GPM-Ka

  7. GPM Ka Minus Ku • Ka has slightly higher sensitivity at all heights • Ku generally less attenuated • No significant difference between the two wavelengths • Toyoshima et al (2015)

  8. Comparing NPOL and GPM Ku NPOL GPM-Ku

  9. Comparing GPM Ku and Ka GPM-Ku GPM-Ka
