| description | In preparation for the launch of the first six satellites of the COSMIC-2
mission in equatorial orbit, and the larger number of observations that such
a mission will provide in the lower tropical troposphere, work is underway
at the National Oceanic and Atmospheric Administration (NOAA) to improve the
assimilation of radio occultation (RO) observations, particularly in the
lower tropical troposphere. As part of the improvement of the bending angle
forward operator at the National Centers for Environmental Prediction
(NCEP), additional quality controls aimed to detect and reject observations
that might have been affected by super-refraction conditions have been
implemented and tested. The updated quality control procedures also address
the situation where the model detects atmospheric super-refraction
conditions. This paper describes the limitations of the current standard
quality controls and discusses the implementation of additional quality
control procedures to address the limitations of assimilating observations
likely affected by the super-refraction conditions, either in the model
simulation or in the retrieval process. |
