The next session focussed on surface retrievals. Bernard Pinty of the Joint Research Centre described the use of an algorithm based on the MISR surface retrieval approach that has been proposed for operational reprocessing of Meteosat data to retrieve surface albedo and aerosol optical depth simultaneously. Catherine Moroney of the University of Arizona first described several performance improvements that have recently been made to the MISR cloud-height stereo retrieval algorithms. Peter Muller then discussed application of the MISR stereo retrieval algorithms to ATSR-2 data. Roger Marchand of Pennsylvania State University then presented results from the AirMISR Alaska deployment.
Potential causes are under investigation.
Tamas Varnai of the University of Arizona showed good agreement between cloud models and the AirMISR BRFs, however, the corresponding albedos are somewhat higher than expected. This is also being investigated. Upgrades to the MISR flight software have been made to rectify several anomalies observed in earlier testing at Valley Forge. Susan Barry of JPL talked about MISR instrument operations and requested inputs from the Science Team on finalizing the Local Mode site list. Thomas Pagano of JPL presented the status of development of the MISR-2 prototype camera to be built under the Instrument Incubator Program.
