The hand-drawn Weekly Snow and Ice Chart of the Northern Hemisphere -- NOAA's longest-running operational satellite product -- has given way to more modern interactive computer techniques to improve product quality, the Commerce Department's National Oceanic and Atmospheric Administration said today.
The Satellite Analysis Branch of NOAA's
Satellite, Data, and Information Service first began generating
Northern Hemisphere Weekly Snow and Ice Cover analysis charts
derived from NOAA's GOES
visible satellite imagery in November 1966. By measuring the
fluctuations in snow and ice patterns during the year and comparing
with other periods, the product initially provided valuable data
for climatic research.
As a result of increasing customer needs
and expectations, NOAA decided to design and implement an efficient,
interactive workstation application. The hand-drawn chart required
six to nine hours of production time per week; the new Interactive
A commemoration was held on May 27 to observe the end of the Weekly Northern Hemisphere Snow and Ice Chart. Satellite Analysis Branch employee Thomas Baldwin remarked, "We will miss it, but not too much we like the interactive computer age!"
