| Zusammenfassung |
| This paper mainly focuses on the validation of temperature estimates derived
with the newly launched Constellation Observing System for Meteorology
Ionosphere and Climate (COSMIC)/Formosa Satellite 3 (FORMOSAT-3) system. The
analysis is based on the radio occultation (RO) data samples collected
during the first year observation from April 2006 to April 2007. For the
validation, we have used the operational stratospheric analyses including
the National Centers for Environmental Prediction - Reanalysis (NCEP), the
Japanese 25-year Reanalysis (JRA-25), and the United Kingdom Met Office
(MetO) data sets. Comparisons done in different formats reveal good
agreement between the COSMIC and reanalysis outputs. Spatially, the largest
deviations are noted in the polar latitudes, and height-wise, the tropical
tropopause region noted the maximum differences (2–4 K). We found that
among the three reanalysis data sets the NCEP data sets have the best
resemblance with the COSMIC measurements. |
