Climate Observations & Analysis Review

April 11-13, 20072

National ClimaticData Center (NCDC)Asheville, North Carolina NCDC is the steward of the Nation’s in-situ

and satellite data and information. Collocated with the U.S. Air Force and Navy

Climatology offices. The three agencies fulfill much of the Nation’s climate data & information requirements.


April 11-13, 20073

Mission Statement

To provide access and

stewardship to the Nation’s

resource of global climate

and weather related data

and information, and assess

and monitor climate

variation and change.


April 11-13, 20074

NCDC Data Base Build Reanalysis effort to develop a

homogeneous 23-year satellite record – Tropical cyclone intensity historically

estimated from “best track” data many inherent temporal heterogeneities

– New data set - from > 20 satellites;14 formats– Removed intra-series & temporal biases– 1983-2005 data: ~169K images; ~2000

storms– Annual update after “Best Track” data

released working to fill in 1981-1983

Example images from New Data set

Univ. of Wis. Analysis Partnership

Objective algorithm develop to work with new data set

– Principal components of azimuthally averaged Tb used to estimate intensity

– Similar to objective Dvorak technique; valid in all ocean basins

Observed Results– PDI increasing in North Atlantic– No significant global trends – “UWis / NCDC” intensities have little

temporal bias
