  1. Aerosol Characterization and Aerosol-Cloud Interaction Derived from Joined Inversion of CALIPSO-MODIS data 05-CldSat-CAL-65 Annual report 2007 Lorraine Remer NASA/GSFC With Roberto Fernandez-Borda/UMBC J.

  2. Year 1 Objectives and Results Objective 1. Reconstruct Kaufman joint MODIS-LIDAR aerosol retrieval from various notes and spreadsheets. Objective 2. Apply retrieval to airborne lidar data and compare retrieval with auxillary measurements. Specifically apply the retrieval to HSRL lidar collected during the MILAGRO campaign. Year 1 results: - Retrieval is up and running - Retrieval reproduces aerosol extinction profile measured by other instruments. - Retrieval reproduces total column fine mode fraction retrieved by MODIS alone - Retrieval does not match fine mode fraction profiles of other instruments

  3. March 10, 2006 MILAGRO Fernandez-Borda Kaufman retrieval Kaufman retrieval using HSRL combined with MODIS reproduces extinction profile. This is NOT guaranteed in the retrieval.

  4. Kaufman retrieval does not appear to match vertical profile of fine mode fraction of other measurements Kaufman • However, • - integrated fmf (0.56) • matches MODIS retrieval (0.58) • other measures of fmf NOT • defined the same way. • other measures do not agree • with each other Fernandez-Borda

  5. Objectives for Year 2 - Continue to evaluate Kaufman retrieval with HSRL opportunities. Understand better the reasons fmf profiles do not match other measurements. - Attempt to apply retrieval to Calipso data in situations where evaluation against other measures are possible.
