Satellite validation for SAGE III (contribution to VINTERSOL/SOLVE-2)

Updated 2003-03-04

In december 2001 the SAGE III experiment was successfully launched. The NASA science team of the SAGE III experiment has announced the Koldewey-Station in Ny-Aalesund as "anchor site" for validation, especially for such parameters as optical depth, aerosol extinction profiles and ozone profiles. Because of time coincidence NASA apprechiates support for the prospected validation activities for ENVISAT. This should be also considered as contribution to the NASA accepted project "Ground based Validation of SAGE III by the NDSC Primary Station at Ny-Ålesund, Spitsbergen" for SOLVE-2.

Comments and additional information:

During the SOLVE/THESEO 2000 campaign and the following ASTAR campaign all instruments, that should be used for SAGE III validation, have already been used. Both campaigns were successful, the experiences and routines should be used again. No major changes on hard- and software are anticipated. First measurements with ozone-lidar and ozone sondes for validation of SAGE III ozone-profiles were carried out in autumn 2001.

Methods & Procedures

Procedures and methodology used for, e.g., sampling and sample storage, sample pretreatment, extraction and analysis, including which laboratories are involved, references to methods employed, etc.

The instrumentation in our NDSC-observatory (infrared-spectrometer, ozone- and aerosol-lidar, photometer, ozone-sondes, UV-spectrometer) shall be used for measuring stratospheric trace gases. Main concern for SAGE III validation will be ozone-measurements by means of lidar and sondes, as well as solar and star photometer and aerosol-lidar measurements. In case of PSC balloon borne aerosol sondes shall be launched.

Additional Information

Is this a bi- AND multi-lateral project (i.e. a project involving cooperation between different countries)?
Yes
Other institutes involved in the project

University Bremen NASA Langley Research Center (Larc)
