Intermountain West Climate Summary (IWCS): Climate information is widely scattered on the web and other locations and consequently water managers and other climate sensitive sectors have requested a single monthly summary of climate information. The Intermountain West Climate Summary releases updated climate and water resource information including precipitation, temperature, snow water equivalent, long-lead temperature and precipitation outlooks, reservoir levels and streamflow forecasts. Researchers Ray, Lowrey, Averyt, Malmberg, Udall.
Colorado (and Interior Southwest) forecasts (experimental guidance)
This website consists of six parts: Status and Outlook for ENSO (El Niño/Southern Oscillation), the most important global climate variability factor on year-to-year time scales; background information on regional climate variability of the interior western U.S., and pertinent ENSO associations; “official" CPC (Climate Prediction Center) forecasts; experimental seasonal forecasts for precipitation in the interior western U.S.; discussion of rainfall forecasts, and useful links to shorter-term forecasts; and executive summary of this webpage. Klaus Wolter, ESRL, NOAA.
South Platte Regional Assessment Tool (SPRAT)
Draining the northeast quadrant of Colorado, the South Platte River Basin covers approximately 20 percent of the state and houses roughly 70 percent of its population, including the Denver-Metro area and Front Range cities to the north. SPRAT models the movement and allocation of water throughout the Basin, allowing users to make relative comparisons of the water supply and demand impacts associated with various population growth, climate/hydrologic, and agricultural land-use scenarios, and by allowing the merits of various water management alternatives (adaptations) and infrastructure changes to be similarly compared. Chris Goemans, Colorado State University.
Colorado River Climate Primer. This publication summarizes Paleo-climate, current climate patterns and future climatology projections for the Colorado River Basin Researchers Udall, Woodhouse, Lowrey.
Grand Canyon Adaptive Management. This study develops forecasts of late-summer storms and associated sediment input into the Grand Canyon to support multi-stakeholder adaptive management experiments aimed at sustaining ecological, cultural and recreational activities. This work is in collaboration with the Grand Canyon Monitoring and Research Center. Researchers Jain, Pulwarty, Eischeid.
Current and Anticipated Precipitation Anomalies over the U.S.
The purpose of this website is to monitor current and anticipated precipitation anomalies over the contiguous United States. Anticipated precipitation anomalies are those which might be expected over approximately the next 2 weeks to 6 months, based on operational or experimental forecasts. Gary Bates, ESRL, NOAA
Reservoir Management Decision Calendar.
Graphically depicts the annual decisions of reservoir operators based on whether they relate to planning, operations or may be affected by climate and weather forecasts. Andrea Ray, ESRL, NOAA, Robert Webb, NOAA.
TreeFlow: Tree-ring reconstructions of streamflow for Colorado.
Provides information about how tree rings are used to extend hydrologic records, and provides access to 20 reconstructions of streamflow gagaes across Colorado. For more information, also see the WWA Tree-ring reconstructions of streamflow pages. Connie Woodhouse, University of AZ, Jeff Lukas, INSTAAR, Robert Web, NOAA
Climate Services Clearinghouse.
The Climate Services Clearinghouse draws together climate services and products across sectors, from NOAA, non-NOAA government agencies, academia, and the private sector, enabling providers to identify and fix overlap and gaps in existing services. It also enables site visitors to locate any service of interest. Genevieve Maricle, Roger Pielke, Jr., University of CO.
