These Oyster data were gathered and utilized during the Response and Assessment phases of the Deepwater Horizon oil spill in the Gulf of Mexico. These data are for the American or Eastern oysters and oyster reefs found in the Gulf. It includes discrete samples, field observations, field photographs and related files originating from the Oysters Technical Working Group (TWG).

These Submerged Aquatic Vegetation data were gathered and utilized during the Response and Assessment phases of the Deepwater Horizon oil spill in the Gulf of Mexico. These data are for the rooted vascular plants such as seagrasses and freshwater/brackish species that grow in the intertidal and subtidal zones. It includes discrete samples, field observations, field photographs and related files originating from the Submerged Aquatic Vegetation Technical Working Group (TWG).

These Shallow Water Coral Reefs data were gathered and utilized during the Response and Assessment phases of the Deepwater Horizon oil spill in the Gulf of Mexico. These data are for the health of shallow water coral reefs in the Gulf. It includes discrete samples, field photographs and related files originating from the Shallow Water Coral Reefs Technical Working Group (TWG).

These Shoreline data were gathered and utilized during the Response and Assessment phases of the Deepwater Horizon oil spill in the Gulf of Mexico. These data are for the salt and brackish marsh, tidal mudflats, mangroves and sandy beaches. It includes discrete samples, field observations, field photographs and related files originating from the Shorelines Technical Working Group (TWG).

These Water Column and Invertebrates data were gathered and utilized during the Response and Assessment phases of the Deepwater Horizon oil spill in the Gulf of Mexico. These data are for the plankton, neuston and micronekton that move through the water column. It includes discrete samples, field observations, field photographs and related files originating from the Water Column and Invertebrates Technical Working Group (TWG).

In March 2015, data for thirteen Alaskan climate divisions were added to the NClimDiv data set. Data for the new Alaskan climate divisions begin in 1925 through the present and are included in all monthly updates. Alaskan climate data include the following elements for divisional and statewide coverage: average temperature, maximum temperature (highs), minimum temperature (lows), and precipitation. The Alaska NClimDiv data were created and updated using similar methodology as that for the CONUS, but with a different approach to establishing the underlying climatology.

Service Records and Retention System (SRRS) is historical digital data set DSI-9949, a collection of products created by the U.S. National Weather Service (NWS) and archived at the National Centers for Environmental Information (NCEI) [formerly National Climatic Data Center (NCDC)]. SRRS was a network of computers and associated hardware whose purpose was to transmit and store a large number of NWS products and make them available as needed.

U.S. Monthly Climate Normals (1971-2000) (DSI-9641C) include climatological normals based on monthly maximum, minimum, and mean temperature and monthly total precipitation records for each year in the 30-year period 1971-2000. DSI-9641G include climatological normals based on monthly and annual heating and cooling degree days. In order to be included in the normals, a station had to have at least 10 years of monthly temperature data or 10 years of monthly precipitation data for each month in the period 1971-2000.

The U.S. Daily Climate Normals (DSI-9641D) are based on monthly maximum, minimum, and mean temperature and monthly total precipitation records for each year in the 30-year period 1971-2000, inclusive (as well as separately computed monthly degree day totals). The monthly values are available in data set DSI-9641C or publication online (Climatography of the United States, No. 81 Monthly Station Normals of Temperature, Precipitation, and Heating and Cooling Degree Days, 1971-2000).

Local Climatological Data (LCD) contains summaries from major airport weather stations that include a daily account of temperature extremes, degree days, precipitation amounts and winds. Also included are the hourly precipitation amounts and abbreviated 3-hourly weather observations. This is the final quality controlled copy and generally has a one to two month time lag. The local climatological data annual file is produced from the National Weather Service (NWS) first and second order stations. These data are contained in the LCD monthly and annual publications.
