The state of the atmosphere as inferred from the FGGE satellite observing systems during SOP-1

Abstract: The statistical properties, and coverage, of satellite temperature sounding data are described Tropical regions are observed every two days, extratropics from one to four times a day Oceans are covered two to three times a day Asynoptic coverage is comparable to the US rawinsonde network twice daily coverage Lack of ground truth for data sparse areas makes accuracy difficult to assess The rms differences of layer mean temperatures obtained from collocating rawinsonde observations with satellite temperature profiles in space and time differ from rms differences of layer mean satellite temperature soundings The FGGE satellite systems can infer the three dimensional motion field and improve the representation of the large scale state of the atmosphere
