Spatial information of climatological frequency distribution daily precipitation is highly valuable for a wide range applications. Accurate estimation climatology can be made gauged locations where quality and lengthy observations are available. For ungauged or poorly locations, however, indirect needed. One approach to use gridded dataset derived from interpolating observations. However, data ...

This report examines the e ect of model bias within a data assimilation sys tem For this study we use the Goddard Earth Observing System GEOS Data Assimilation System DAS which employs the Incremental Analysis Updating IAU procedure In such a procedure the after analysis minus rst guess in crements are used as external forcing within a general circulation model GCM to provide corrective adjustm...

[1] A dynamical downscaling of the 6-hourly 1948–2006 NCEP/NCAR re-analyses for the subarctic region of the North Atlantic has been used to derive a climatology of polar lows by means of a tracking algorithm based on the simulated bandpass filtered MSLP-fields. This climatology is consistent with the limited observational evidence in terms of frequency and spatial distribution. The climatology ...

Blended satellite–ship evaporation and SSM/I retrieved precipitation fields are used to compute oceanic freshwater budget (FWB) and transport (FWT) over a 3-year period (1988–90). In order to validate the results, comparisons on monthly, seasonal, and multiyear average bases are performed with ECMWF analyzed field and climatology respectively. For May 1988, differences between ECMWF output and ...

[1] Global maps of the Earth’s surface Lambertian equivalent reflectance (LER) are constructed using 3 years of Ozone Monitoring Instrument (OMI) measurements obtained between October 2004 and October 2007 at 23 wavelengths between 328 and 500 nm. The maps are constructed on a 0.5 by 0.5 longitude-latitude grid for each calendar month using an algorithm based on temporal histograms of the obser...

In this article we prove the endogeny and bivariate uniqueness property for a particular “max-type” recursive distributional equation (RDE). The RDE we consider is the so called logistic RDE, which appears in the proof of the ζ(2)-limit of the random assignment problem using the local weak convergence method proved by D. Aldous [Probab. Theory Related Fields 93 (1992)(4), 507 – 534]. This artic...

The Congo Basin is one of three key convective regions on the planet which, during the transition seasons, dominates global tropical rainfall. There is little agreement as to the distribution and quantity of rainfall across the basin with datasets differing by an order of magnitude in some seasons. The location of maximum rainfall is in the far eastern sector of the basin in some datasets but t...

This paper discusses the extent to which the science of urban climatology has informed local climate change strategies in four city case studies – Stuttgart, Tokyo, New York City, and Manchester. The paper draws on historical and contemporary policy documents along with 60 interviews with practitioners, city officials, politicians, and academics in order to understand the use or non-use of urba...
