Oxford MIPAS meeting#103
03 October 06

Present

Instrument Status [Prev] [Next]
Envisat problem with Ka band antenna since 26 Sep06 (more details on the Envisat Web-Site). This is the antenna that transmits data via the Artemis relay satellite allowing continuous transmission of payload data. From 01 Oct ESA have reverted to their original scheme (used before Artemis was operational) of transmitting 9 orbits in near-real-time to Kiruna with the remaining 5 orbits collected at Svalbard for later distribution.

MIPAS itself should now have started a long sequence of nominal mode observations 2 orbits on followed by 3 orbits off (intended to be tested as an input for ECMWF data assimilation).

Middle Atmosphere Mode (AD) [Prev] [Next]
Microwindow selection for MA mode observations (29 sweeps from 18-102km @ 3km steps). Intention is to use these to retrieve mesospheric data taken Jan 10-15 2005.

New DPhil Students
Luis Millan-Valle will be working on mesospheric observations from MIPAS and HIRDLS
Corwin Wright will be working on HIRDLS measurements
