We use moderate resolution satellite data to assess live fuel condition for estimating fire danger. Using 23 years of vegetation condition measurements, we are able to determine the relative greenness of wildland vegetation susceptible to burning.
Consistent, historic, and up-to-date water-quality data, such as temperature, specific conductance, pH, nutrients, pesticides, and volatile organic compounds downloadable from the USGS National Water Information System as graphs, tables, or files.
Explains the strategy that USGS will use to estimate the distribution and abundance of freshwater resources, evaluate factors affecting availability, estimate undeveloped potential resources, and forecasting likely changes due to other factors.
