Meteorological data provide information on atmospheric conditions that can affect water quality and biological and physical processes. Core elements currently measured at each National Estuarine Research Reserve (NERR) include air temperature, relative humidity, barometric pressure, wind speed, wind direction, rainfall, and photosynthetically active radiation (PAR). Optional parameters include total solar radiation. Each site maintains at least one meteorological station. Stations are placed at locations typical of local conditions or in areas where a specific need for weather data has been identified. Data are reported at 15 minute intervals. Prior to 2007, hourly and daily average data were also reported. Water quality observations made over long time periods can provide important feedback to scientists and to local, state, and national resource managers about actions taken to manage, protect, and restore estuaries. They also provide valuable information for evaluating the impacts of environmental change on coastal habitats and species. There are at least four water quality stations at each National Estuarine Research Reserve. Each station is designed to characterize long-term variability and short term changes in environmental conditions. Data are collected with data loggers at fifteen minute intervals and instruments are deployed continuously and year round where possible. Water quality parameters collected include: water temperature, specific conductivity, salinity, percent saturation of dissolved oxygen, dissolved oxygen concentration, pH, depth, and turbidity. Chlorophyll fluorescence is an optional parameter and pressure corrected water depth is a calculated value. There are at least four water quality stations at each National Estuarine Research Reserve. Each station is designed to characterize long-term variability and short term changes in environmental conditions. Discrete samples for nutrient and chlorophyll a concentrations are collected at each long-term monitoring station at least once monthly. More intensive (24-hours over a complete tidal cycle) sampling is conducted each month at one water quality monitoring station to better understand impacts of tide and irradiance on nutrient cycling. Nutrient parameters collected include: nitrate, nitrite, ammonium, orthophosphate, and chlorophyll a. Numerous optional parameters include dissolved organic carbon, total dissolved nitrogen, and total dissolved phosphorus. All data are provided in yearly .CSV files. To identify and track short-term variability and long-term changes in the integrity and biodiversity of representative estuarine ecosystems and coastal watersheds for the purpose of contributing to effective national, regional and site specific coastal zone management. onGoing historicalArchive NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact HTTPS NCEI Contact Information Information for contacts at NCEI. information pointOfContact asNeeded https://www.ncei.noaa.gov/access/metadata/landing-page/bin/gfx?id=gov.noaa.nodc:NERRS-SWMP Preview graphic PNG 0000789 0019215 0052765 0200366 NCEI ACCESSION NUMBER 2011-10-05 publication AIR TEMPERATURE AMMONIA (NH3) AMMONIUM (NH4) BAROMETRIC PRESSURE CHLOROPHYLL CHLOROPHYLL - RELATIVE FLUORESCENCE CHLOROPHYLL A CONDUCTIVITY DEPTH - OBSERVATION DEPTH - SENSOR DISSOLVED ORGANIC CARBON DISSOLVED OXYGEN FLUORESCENCE NITRATE nitrate + nitrite content (concentration) NITRITE NUTRIENTS pH phosphate PHOTOSYNTHETIC ACTIVE RADIATION (PAR) PIGMENTS PRECIPITATION PRECIPITATION AMOUNT RELATIVE HUMIDITY SALINITY silicate SOLAR RADIATION - ATMOSPHERIC turbidity water depth WATER LEVEL WATER TEMPERATURE WIND DIRECTION WIND DIRECTION - AVERAGE WIND SPEED WIND SPEED - AVERAGE theme NODC DATA TYPES THESAURUS barometric pressure sensor conductivity sensor humidity sensor meteorological sensor multi-parameter water quality sensor oxygen sensor pH sensor pressure gauge pyranometer rain gauge temperature probe thermometer visual observation instrument NODC INSTRUMENT TYPES THESAURUS chemical in situ laboratory analyses meteorological physical site samples time series water chemistry theme NODC OBSERVATION TYPES THESAURUS National Estuarine Research Reserve System Centralized Data Management Office dataCentre NODC COLLECTING INSTITUTION NAMES THESAURUS National Estuarine Research Reserve System Centralized Data Management Office dataCentre NODC SUBMITTING INSTITUTION NAMES THESAURUS National Estuarine Research Reserve System System-wide Monitoring Program (NERRS SWMP) project NODC PROJECT NAMES THESAURUS Caribbean Sea Coastal Waters of Alabama Coastal Waters of California Coastal Waters of Florida Coastal Waters of Gulf of America Coastal Waters of Gulf of Mexico Coastal Waters of Hawaii Coastal Waters of Mississippi Coastal Waters of Southeast Alaska and British Columbia Coastal Waters of Texas Coastal Waters of Western U.S. Great Lakes Gulf of Alaska Gulf of America Gulf of Mexico North American Coastline-North North American Coastline-South North Atlantic Ocean North Pacific Ocean San Diego Bay place NODC SEA AREA NAMES THESAURUS oceanography theme WMO_CategoryCode 2012-09-15 publication DOC/NOAA/NESDIS/NODC > National Oceanographic Data Center, NESDIS, NOAA, U.S. Department of Commerce DOC/NOAA/NOS/OCRM/NERR > National Estuarine Research Reserve, Ocean and Coastal Resource Management, National Ocean Service, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2026 revision 24 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) Greenbelt MD https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords HTTPS GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.

Can be a hand-held instrument or a sonde for unattended monitoring. Often used in coastal water monitoring stations. YSI is the preeminent brand (as of 2024). oxygen sensor oxygen sensor Any instrument that measures oxygen content in a compound. pH sensor pH sensor generic meter used to measure pH Any of a class of instruments used to quantify pH in a water or other type of sample. pressure gauge pressure gauge pressure gauge pressure gauge used to measure water pressure for use in NODC File Alias F017 pyranometer pyranometer Instrument that measure solar radiation. rain gauge rain gauge A device to measure the amount of liquid precipitation The definition of liquid precipitation is any form of water falling from the sky as rain. Rain gauge measures the amount of liquid precipitation. temperature probe temperature probe For example, OMEGA temperature probe PR-11-2-100-1/8-6-e Vaisala HUMICAP® Humidity and Temperature Probe HMP155 thermometer thermometer generic thermometer or reversing thermometer use thermometer when temperature is a data type, but the exact instrument used to measure temperature is unknown visual observation visual observation not an instrument - maybe an observation type
