Location of Sampling Stations: Temperature is measured at the opening of the standpipe in the concrete V-flumes in N01B, N04D, N02B, and N20B.

Frequency of Sampling: Temperature (oC) values are recorded hourly. Data is dumped at approximately weekly to biweekly intervals (see data set ASD02).

Methods: Thermocouple wire (copper-constantan) is connected to Channel 2 of the CR-21X data logger (Campbell Scientific Co.). Beginning April 1986 (July 1 for N20B), the CR-21X is programmed to include instructions for hourly recording of stream temperature (see data set ASD02). The CR-21X is internally calibrated for copper-constantan wire; recorded temperatures are verified by direct thermometer measurements at approximately weekly intervals (see data set AWT01). The computer program 'streamtmp.com' (Pascal program on IBM PC) reads the raw data file as recorded by the CR-21X and generates the output data file.

Form of Data Output: Files of the form 'AWT021A.86', 'AWT021B.86', etc., contain hourly temperature values for each flume for each year. Note that a value is recorded regardless of whether there is flow across the flume; thus, these files must be compared to corrected stream discharge (ASD02) values so that temperature data for no flow conditions can be deleted.
