datey -- designates the year column for array based data loggers dated -- designates the julian day column for array based data loggers dateh -- designates the time column for array based data loggers tmstmpcol -- Identifies the ISO format date/time found in table based data loggers.
Numerical Functions
num -- assumes the value coming from the logger already has proper units etc and any data checking is of a qc nature. net -- assumes the value coming from the logger already has proper units etc and any data checking is of a qc nature. precip -- assumes the value coming from the logger already has proper units etc and any data checking is of a qc nature. (should augment this 12/2016) therm -- assumes the value is a thermistor resistance with units of kilo-ohms. coef_1 = Steinhart-Hart A value coef_2 = Steinhart-Hart B value coef_3 = Steinhart-Hart C value coef_4 = Freezing Point Offset (degrees Celsius) returns a value in degrees Celsius thermF -- same options as therm but returns degrees Fahrenheit therm1 -- similar to therm but rather than coefficients being specified in coef_1 - coef_3, a text file with a look up table of resistance vs coefficients is used. therm2 -- same as therm1 but for a second thermistor type therm3 -- same as therm1 but for a third thermistor type poly -- applies an up to 6th order polynomial to the value from the data logger. Use coef_1 - coef_7 to set coefficient values. rh -- identifies variable as a relative humidity sensor. Additional relative humidity checks are applied in QC. (values over 100%) swrad -- identifies variable as a shortwave radiometer. Additional checks are applied (night time values below 0 W/m^2) rt_sensor -- another type of radiation calibration. coef_1 = divisor value coef_2 = offset value coef_3 = multiplier value equation = self.result = ((self.variable / self.div) + self.offset) / self.mult sm -- same as poly but then multiplies the result by 100 to convert to percent.
Functions that use two or more data elements in processing
mrctherm -- converts millivolt output to temperature in degrees Celsius for MRC type thermistor strings. coef_3 = specify the data column with reference voltage here. netrad -- converts millivolt output for Q7 Rebs Net Radiometer to W/m^2. coef_1 = positive calibration coefficient coef_2 = negative calibration coefficient coef_3 = specify the data column with reference wind speed
