“…This drought affected early-and midseason crops mostly in the Midwest. Kansas had the lowest wheat yield since 1967 (LeComte 1990). Because the 1989 drought was regional, the average U.S. wheat yield was reduced by only 8%.…”

“…During May and June the VCI showed a reduction of drought area. In the northeastern United States, where some measures to mitigate drought had been already initiated (LeComte 1990), this reduction occurred very quickly (compare weeks 19 and 23, Fig. 13) following heavy showers in the first 15 days of May (Fig.…”

“…The 1989 weather was favorable for vegetation growth. Across the nation precipitation during observed in Kansas and Nebraska (LeComte 1990). This agreed with VCI estimates of drought extent and time of its impacts.…”

Drought is one of the most adverse and powerful weatherrelated disasters that occur every year across a portion of the United States. The consequences of droughts quite often can be devastating. To mitigate these consequences, droughts require careful monitoring. Recently, NOAA's National Environmental Satellite Data and Information Service developed a new Advanced Very High Resolution Radiometer-based vegetation condition index (VCI) that showed good results when it was used for drought detection and tracking. The VCI is a vegetation index with reduced noise and is adjusted for land climate, ecology, and weather conditions. This index provides a quantitative estimate of weather impact on vegetation and also measures vegetation conditions. Several large-area experiments showed that the VCI had excellent ability to detect drought and to measure the time of its onset and its intensity, duration, and impact on vegetation. The VCI provides accurate drought information not only for the cases with welldefined, prolonged, widespread, and very strong droughts, but also for very localized, short-term, and ill-defined droughts. The advantages of this index compared to conventional ground data are in providing more comprehensive, timely, and accurate drought information. This paper describes the methodology and technical principles used to derive the vegetation condition index, explores data processing, and gives many examples of VCI application for drought monitoring in the United States during 1985-90. The spatial and temporal patterns of VCI-derived drought were in a very good agreement with the identical patterns identified from precipitation and yield anomalies.
