Monitoring Vegetation Drought Stress

Home

Climate change is expected to alter precipitation patterns worldwide, potentially increasing chances for drought in places where rainfall decreases over extended periods. Currently, droughts are responsible for $6 to $8 billion in losses each year in the United States alone. Accurate monitoring of drought conditions is vital in helping to mitigate drought impacts.

VegDRI

VegDRI

The VegDRI is a hybrid drought index that incorporates multiple sources of input data informative of drought stress.

QuickDRI

QuickDRI

Similar in methodology to VegDRI, QuickDRI is a hybrid drought index that incorporates multiple sources of input data informative of drought or rapidly drying conditions.

QuickDRI, VegDRI Showed Their Value in Montana Drought of 2017

In the spring of 2017, almost no one in Montana saw the drought coming. Not when winter snowpack and early rains soaked the landscapes with adequate moisture. Not when springtime green-up seemed to hold such promise.

Exploring the regional dynamics of U.S. irrigated agriculture from 2002 to 2017

The United States has a geographically mature and stable land use and land cover system including land used as irrigated cropland; however, changes in irrigation land use frequently occur related to various drivers. We applied a consistent methodology at a 250 m spatial resolution across the lower 48 states to map and estimate irrigation dynamics...

Exploring VIIRS continuity with MODIS in an expedited capability for monitoring drought-related vegetation conditions

Vegetation has been effectively monitored using remote sensing time-series vegetation index (VI) data for several decades. Drought monitoring has been a common application with algorithms tuned to capturing anomalous temporal and spatial vegetation patterns. Drought stress models, such as the Vegetation Drought Response Index (VegDRI), often use...

Assessing the evolution of soil moisture and vegetation conditions during the 2012 United States flash drought

This study examines the evolution of several model-based and satellite-derived drought metrics sensitive to soil moisture and vegetation conditions during the extreme flash drought event that impacted major agricultural areas across the central U.S. during 2012. Standardized anomalies from the remote sensing based Evaporative Stress Index (ESI)...
