Variables:
datetime = date and time doy = day of year (nominalDay) time = time of day (nominalHour) sap.tsca = hemlock sap flow (average of three trees) scaled to projected canopy area (millimolePerMeterSquaredPerSecond) sap.acru = red maple sap flow (average of three trees) scaled to projected canopy area (millimolePerMeterSquaredPerSecond) sap.quru = red oak sap flow (average of three trees) scaled to projected canopy area (millimolePerMeterSquaredPerSecond) photo.tsca = hemlock photosynthesis (average of three trees) scaled to projected canopy area (micromolePerMeterSquaredPerSecond) photo.acru = red maple photosynthesis (average of three trees) scaled to projected canopy area; times when trees were leafless shown as "NA" (micromolePerMeterSquaredPerSecond) photo.quru = red oak photosynthesis (average of three trees) scaled to projected canopy area; times when trees were leafless shown as "NA" (micromolePerMeterSquaredPerSecond) airt = air temperature (celsius) rh = Relative humidity, % (number) wind1 = wind speed in upper canopy (metersPerSecond) wind2 = wind speed in lower canopy (metersPerSecond) t1tsca = hemlock leaf temperature in upper canopy (celsius) t2tsca = hemlock leaf temperature in lower canopy (celsius) t1acru = red maple leaf temperature in upper canopy; times when trees were leafless shown as "NA" (celsius) t2acru = red maple leaf temperature in lower canopy; times when trees were leafless shown as "NA" (celsius) t1quru = red oak leaf temperature in upper canopy; times when trees were leafless shown as "NA" (celsius) t2quru = red oak leaf temperature in lower canopy; times when trees were leafless shown as "NA" (celsius)
