Fig. 14.From: Performance assessment of radio occultation data from GeoOptics by comparing with COSMIC data3CH estimates of refractivity error standard deviation of radiosonde (pink), ECMWF analysis (yellow), COSMIC-2 (green), GeoOptics (blue). The mean standard deviation of differences between GeoOptics and each of the other data sets is shown with black dash-dotted curve. The counts are shown by the black dotted curveBack to article page
