A review of sources of systematic errors and uncertainties in observations and simulations at 183 GHz
Several recent studies have observed systematic differences between measurements in the 183.31 GHz water vapor line by space-borne sounders and calculations using radiative transfer models, with inputs from either radiosondes (radiosonde observations, RAOBs) or short-range forecasts by numerical wea...

| description | Several recent studies have observed systematic differences between
measurements in the 183.31 GHz water vapor line by space-borne sounders and
calculations using radiative transfer models, with inputs from either
radiosondes (radiosonde observations, RAOBs) or short-range forecasts by numerical weather prediction
(NWP) models. This paper discusses all the relevant categories of
observation-based or model-based data, quantifies their uncertainties and
separates biases that could be common to all causes from those attributable
to a particular cause. Reference observations from radiosondes, Global
Navigation Satellite System (GNSS) receivers, differential absorption lidar (DIAL)
and Raman lidar are thus overviewed. Biases arising from their calibration
procedures, NWP models and data assimilation, instrument biases and
radiative transfer models (both the models themselves and the underlying
spectroscopy) are presented and discussed. Although presently no single
process in the comparisons seems capable of explaining the observed
structure of bias, recommendations are made in order to better understand
the causes. |
