The Cary Institute Environmental Monitoring Program is a long-term program to monitor environmental parameters that are important to natural ecosystems. The program includes monitoring of air, precipitation and stream chemistry as well as meteorological, solar radiation and physical stream parameters. The Cary Institute also hosts sites for two additional programs: The New York State Department of Environmental Conservation Ambient Air Monitoring Program, for ground level ozone and the National Oceanic and Atmospheric Administration (NOAA), U.S....

NCEI Accession 0162256 includes Surface underway, chemical, meteorological and physical data collected from R/V Meteor research cruise along the WOCE SectionAR12/AR24 (EXPOCODE 06MT19970515) in the North Atlantic Ocean from 1997-05-15 to 1997-06-08. These data include measurements of mole fraction of CO2 in the equilibrator headspace (dry) at equilibrator temperature, mole fraction of CO2 measured in dry outside air, barometric pressure in the equilibrator headspace, water temperature in equilibrator, sea surface temperature, sea surface salinity and...

Measuring instrumentMaisbich basin: V-notch discharge meter Q1Type: Pressure Sensor Keller DCX-4.0, SN 1454This instrument is based on differential pressure measurement of two absolute sensors. The sensors measure pressure and temperature.Height of V-notch above sensor: hV=0.145m.The discharge is calculated with the rating curve Q=C*(h-hV)^2.5 where C is a calibration constant and h results from the pressure difference (Willem Luxemburg, Martijn Westhoff).

Explanation of the calibration procedure of the DTS derived temperatures in the Maisbich river, Luxembourg.Note that it only corrects offsets orriginating from the DTS device (Halo, Sensornet, UK). It does NOT correct for periods when the cable is not properly submerged in the stream.The DTS obtained temperatures were calibrated with five independent temperature loggers (TidbiT v2 Temp logger, HOBO, USA) located along the cable at 26, 395, 931, 1111 and 1270 m from the DTS...
