Good day, I want to obtain the moisture bugdet term P - E from the evapotranpiration and Total
precipitation data sets, and the evaporation values are negative.
I'm always a bit amused at those who promote AGW, and the media who support them, continue to use emotive, evocative words in their descriptions of mathematic statistical functions of temperatures and / or
precipitation data sets.

The environmental
data sets from the Tropical Rainfall Measuring Mission and the MODIS sensors will continue into the next decade with
data provided by their follow - on missions: the Global
Precipitation Measurement mission to launch in early 2014, and the Visible Infrared Imaging Radiometer Suite on the Suomi National Polar - orbiting Partnership satellite currently in orbit.
Diving deeper into the complex puzzle of mass strandings, the team decided to expand their analysis and include additional oceanographic and atmospheric
data sets from NASA's Earth science missions, including Terra, the Sea - viewing Wide Field - of - view Sensor — or SeaWIFS, for short — and Global
Precipitation Measurement, as well as the National Oceanic and Atmospheric Administration's Geostationary Operational Environmental Satellite, or GOES, mission.
A clear and more detailed explanation can be found in Section 2.1 of the Simmons et al 2010 JGR article «Low - frequency variations in surface atmospheric humidity, temperature, and
precipitation: Inferences from reanalyses and monthly gridded observational
data sets» (doi: 10.1029 / 2009JD012442).

In his talk, he discussed how to catalogue the occurance of extreme
precipitation across British Columbia, using a new comprehensive
data set from Environment Canada, in order to create a climatological baseline.
Exceptions were the Norwegian west coast, with much above average
precipitation, and a small band south of the Baltic stretching towards the Black Sea with above average
precipitation, the latter present in both
data sets, but more pronounced in E-OBS.
The DHM
data set includes daily flow
data for 44 river gauging stations for the period 1964 - 2000, 258 daily
precipitation records covering 1956 - 1996, 119 daily and monthly temperature records spanning the period 1934 - 1996, 114 records of average monthly humidity from 1967 - 1997, and 41 records with average monthly values of sunshine hours between 1967 - 1997...
Relatively little detailed work has compared such reanalysis
data with independent observed
data sets (see Santer et al., 1999, and Widmann and Bretherton, 2000, for two exceptions), but it is known that certain reanalysis variables - such as
precipitation and some other hydrological variables - are unreliable.
Using
precipitation data from the University of East Anglia and ocean temperatures from the Hadley Centre combined with climate models, the researchers were able to add or omit the oceanic temperatures and compare the two
sets of results.
