TreeFlow is a comprehensive web resource for tree-ring reconstructions of streamflow and climate, providing easy access to reconstruction data as well as information about how the data were developed, and can be used. Originally developed by researchers at the Climate Assessment for the Southwest, TreeFlow has a growing collection of tree ring constructions for river basins throughout the Western United States.
Arizona DroughtWatch is a tool designed by the Climate Assessment for the Southwest to collect, summarize, and display timely observations of drought impacts across Arizona. The tool was developed to support drought monitoring efforts spearheaded by county-level Local Drought Impact Groups organized in support of the Arizona State Drought Preparedness Plan.
The longest instrumental climate records date back only about 100 years in the Southwest, a timeframe that likely does not capture the full range of climate variability. Extending the record to earlier times provides additional information on the length and severity of past droughts. This tool created by the Climate Assessment for the Southwest allows users to visualize the climate variability during the past 1,000 years or so in each climate division in Arizona and New Mexico.
The Climate Assessment for the Southwest puts out monthly outlooks for the region. These outlooks include a look at last month's temperature and precipitation data, the current state of El Niño/La Niña and reservoir levels, and forecasts for temperature, precipitation, and streamflow. Additional seasonal sections of the outlook include wildland fire and snowpack updates. Archives are also available online.
