NOTICE: Given the large size of the MACAv2METDATA dataset, and a known issue with the data server being used to host it, initial load times may take a very long time and / or time out. Subsequent requests should be faster due to caching, but the cache clears periodically and the dataset must be rescanned prior to access. We are working on a fix for this issue. In the mean time, please use the dataset with care and make sureyou've reviewed the GDP scalability guidelines. https://my.usgs.gov/confluence/display/GeoDataPortal/Geo+Data+Portal+Scalability+Guidelines This archive contains daily downscaled meteorological and hydrological projections for the Conterminous United States at 1/24-deg resolution utilizing the...
This project used species distribution modeling, population genetics, and geospatial analysis of historical vs. modern vertebrate populations to identify climate change refugia and population connectivity across the Sierra Nevada. It is hypothesized that climate change refugia will increase persistence and stability of populations and, as a result, maintain higher genetic diversity. This work helps managers assess the need to include connectivity and refugia in climate change adaptation strategies. Results help Sierra Nevada land managers allocate limited resources, aid future scenario assessment at landscape scales, and develop a performance measure for assessing resilience.

USGS developed The National Map (TNM) Gazetteer as the Federal and national standard (ANSI INCITS 446-2008) for geographic nomenclature based on the Geographic Names Information System (GNIS). The National Map Gazetteer contains information about physical and cultural geographic features, geographic areas, and locational entities that are generally recognizable and locatable by name (have achieved some landmark status) and are of interest to any level of government or to the public for any purpose that would lead to the representation of the feature in printed or electronic maps and/or geographic information systems. The dataset includes features of all types in the United States, its associated areas, and Antarctica,...

Historical land use/land cover for 2005. Spatial and temporal distributions of current and projected land-use and land-cover (LULC) changes are essential in modeling future potential carbon storage and fluxes within the nation's major ecological regions (Zhu and others, 2010). Annual raster-based maps of future LULC conditions for the years 2006 to 2100 were created based on historical LULC conditions combined with the Intergovernmental Panel on Climate Change Special Report on Emissions Scenarios (IPCC-SRES) scenario elements to develop four distinct, equally plausible outcomes. The historical LULC baseline conditions were derived from 1.) a modified version of the 1992 National Land Cover Dataset (http://www.epa.gov/mrlc/nlcd.html),...

This collection contains three statistically downscaled time series (datasets) for the Red River Basin (South Central U.S.), and one dataset used as historical observations. In particular, three different Global Climate Models (MPI-ESM-LR, CCSM4 and MIROC5) were downscaled using three different quantile mapping methods (CDFt, EDQM and BCQM). We do not recommend the use of the BCQM method, as the CDFt method is considered an improvement of it. The datasets created using the BCQM method are published as a demonstration of the risks of using flawed methods. The variables of interest are: daily maximum and minimum temperature, and daily precipitation. The spatial resolution of the datasets in the collection is 1/10th...

Included are samples of three types of State and Territorial maps: the Holt's maps, the US Department of Interior maps and the Transportation/Postal Route maps. The Holt's maps were produced between 1883 and ca.1890. They show the development and settlement of Wyoming and include the location of some early ranches and trails. The Archives has US Department of Interior State maps from 1876 to 1947. They are extremely detailed, including information as diverse as the location of US land offices, Indian and Military Reservations, forest and bird reserves, etc. The Transportation/Postal Route maps vary greatly depending on the reason they were produced. Many of the early Postal Route maps don't even show roads or trails,...
