Measurement Species of ILAS-II Vertical profiles (ILAS-II: solar occultation sensor)

in polar regions (ADEOS-II: sun-synchronous polar orbit)

• Standard Product:

O3, HNO3, NO2, N2O, CH4, H2O, aerosol(vis.)

• Research Product:

ClONO2, N2O5, CFC-12, CFC-11, CO, C2H6, OCS, NO, O3(isotope), aerosol(IR), temperature, pressure

The following simulated latitudes and local times of the ILAS-II measurements were calculated for the initial condition of ADEOS-II orbit elements on 1 November 2001 available from NASDA: The general feature is the same irrespective of specific years.

Stratospheric Meteorological Data

• Acquisition and presentation by CNES Met. Team at Met. Briefing

(including potential vorticity map)

ILAS-II Validation Calendar

• ILAS-II occultation measurements over Kiruna (67.88N, 21.06E) are calculated.

• ILAS-II occultation measurement location depends on an orbit parameter of ADEOS-II, i.e., local suntime of descending of the equator crossing of ADEOS-II, which should be set as

10:30 am +/- 15 minutes. The information for 10:15, 10:30, 10:45 am is given.

• A set of the following validation calendar information was calculated for the initial condition of ADEOS-II orbit elements on 1 November 2001 available from NASDA: The general feature is the same irrespective of specific years.
