Datapro Parameter Options

Date / Time Related

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
