ILAS Campaign, Kiruna, Feb-Mar 1997)
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.
