February 1983
The Special Effort was an attempt at enhancing the basic FGGE level

data set. It focused on removing deficiencies in the objective methods

uality assurance, removing deficiencies in certain types of

operaticnally produced satellite soundings, and removing deficiencies in

certain types of operationally produced cloud tracked winds. The Special

Effort was a joint NASA-NOAA-University of Wisconsin effort. The

University of Wisconsin installed an interactive Mc1DAS capability on the

Amdahl computer at the Goddard Laboratory of Atmospheric Sciences (GLAS)

with one interactive video terminal at Goddard and the other at the World

Weather Building. Witli this interactive capability a joint processing

effort was undertaken to reprocess certain FGGE data sets. NOAA produced a

specially edited data set for the special observing periods (SOPs) of FGGE.

I. NASA produced an enhanced satellite sounding data set for the SOPs while

the University of Wisconsin produced an enhanced cloud tracked wind set

from the Japanese geostationary satellite images.

Under contract NAS 5-25148 the Space Science and Engineering Center

(SSEC) of the University of Wisconsin-Madison produced enhanced cloudtracked winds for the Winter Mcnex (December 1978) period and the First

FGGE Special Observing Period (January-February 1979). This work was

started on 4 .January 1980 and completed on 7 August 1980. Under contract

1. NAS 5-26540 SSEC produced enhanced cloud drift winds for the second FGGE

Special Observing Period (May-June 1979). Work on these data sets was

completed on 12 March 1982. Because of a number of computer problems

i

f [resulting in unantic;pated expenses], it was not possible to totally

complete the entire SOP-II period. We were directed by the NASA technical

monitor to stop processing with the June 27, 1979 data set. The following

is the number of enhanced Special Effort cloud wind measurements made for
each of the five months and the number of measurements originally made by

the operational FGGE processing.

Number of FGGE

Month Operational Winds

December 18,600

January 28,662

February 17,584

May 22,723

Number of Special Effort

72,530

86,669

June (through 27th) 18,549 73,847 

As can be seen by the above table, there was a significent ineiease in

cloud wind yield with the Special Effort.

The cloud wind data sets were written onto computer t: in the FGGE

Level IIb format and shipped to Goddard Space Flight Centel (Jim Edelman)

for inclusion in the Special Effort data set. In addition copies were sent

to Sweden's Level IIb processing center (Stan Orrhagen), to the U. S. FGGE

archive at Ashville (Bob Williams) and to various researchers including K.

Krishnamurti at Flordia State, T. Murakami at the University of Hawaii, W.

Bourke at the Australian 'numerical Meteorology Research Center and T.

Ramada at the Japanese Meteorological Center. The Special Effort data is
