  1. Understanding and Predicting Dangerous Conditions at the Irminger Sea Caused by the Effects of Greenland Tip Jet Events Using NASA Satellite Wind Products Making Earth Science Data Records for Use in Research Environments (MEaSUREs) A Cross-Calibrated Multi-Platform (CCMP) Ocean Surface Wind Product for Meteorological and Oceanographic Applications Principal Investigator: Robert Atlas (NOAA AOML) The CCMP data set combines insitu and cross-calibrated ocean surface winds derived from TRMM TMI, AMSRE, SSM/I, Seawinds and Quikscat (see DISCOVER project) into a consistent high resolution (25km) global analysis every 6-hours using a variational analysis method (VAM). This figure shows the magnitude (shaded area – m/s) and direction (grey streamlines) of the 10-m wind for a particular Greenland tip jet event that occurred between December 21st and 22nd 2002. It is evident that the combination of wind products derived from SSM/I, Quikscat and AMSR-E in the CCMP data set (left panel) shows a more intense tip jet event compared to the ECMWF operational analysis (right panel). Relevance to NASA Goals Impact of CCMP Winds • The CCMP analysis is a significant improvement over current operational analyses in capturing the Greenland Tip Jet events. This is important because: • Tip Jet events cause dangerous conditions at sea • There is mounting evidence that Tip Jet events may be affecting the wider climate system by causing surface waters to cool and sink. NASA Relevance: (1)Pioneers the scientific use of satellite measurements to improve human understanding of our home planet; (2) expands understanding of the Earth system using consistent records; (3) develops the means of utilizing a multitude of data sources to form coherent time series.
