Comparing Global Temperature Trends from Formosat3/Cosmic and Major Meteorological Analyses during the 2006-2015 Period

Project Details


As detailed in the United Nations (UN) Intergovernmental Panel in Climate Change latest report on global climate assessment (IPCC, 2014), temperature is a key parameter driving the climate change. In order to understand current status of climate, and for accessing future climate impacts, accurate assessment is a top priority for climate research. By using satellite radio occultation (RO) technique, the FORMOSAT-3/COSMIC (F3C) satellite is able to achieve a continuous measurements of atmospheric temperature profiles during the 2006-2015 period on a global domain and from surface to 40-km altitude in a consistent way. These profile of measurements provides a valuable dataset to understand global temperature trends during the 2006-2015 period. The F3C RO data has also been continuously assimilated by world’s major meteorological centers such as the European Center for Medium Range Weather Forecast (ECMWF), the United States National Centers for Environmental Predictions (NCEP), and the United Kingdom Meteorological Office (UKMO) for the daily weather forecast. As temperature is a key parameter in current climate parameter (IPCC, 2014). We ask what will be the global temperature trends observed by the F3Ccompared with the meteorological analysis from ECMWF, UKMO, and NCEP? In this proposal we intend to conduct detailed comparisons of the temperature trends between the F3C observations and meteorological analysis. The vertical extent of the comparisons will be made from surface to 40-km altitude, and to cover the 2006-2015 period. The results of these comparisons can help to strengthen the unique features seen by the F3C but may not revealed in the meteorological analysis.
