Almost all of the soil respiration spreadsheets are set up with the following columns: A. Year, B. Julian Day, C. HHMM, D. SEC, E. Signal voltage for CO2 Conc from LiCOR IRGA F. Signal Voltage for IRGA Detector Temperature G. Battery Voltage, H. Data Logger Panel Temperature, I. Calculated LiCOR Temperature, J. Calculated CO2 Concentration in Chamber, K-Q. contain the equations required to calculate flux rate R. Individual measurent site S. Flux T. Succeding columns in the first 50 rows contain summary information for that measurement sequence A few spreadsheets contain only two records of CO2 concentration and time for each measurement due to failure to record datalogger readings.
