EasyFlux DL for CR6CP

v1.08

CR6 datalogger program for Campbell closed-path eddy-covariance systems.

Revision History

v1.08June 13, 2024
  • Corrected a compile error for the CPEC306.
  • Corrected wrong units used for LE flux.
v1.06November 9, 2023
  • CO2 and H2O in a mole fraction in wet air was added to Flux_AmeriFlux_format and CO2 mixing ratio and H2O mixing ratio were moved to Flux_CSFormat.
  • Add the compatibility of pumps for two models.
  • Revise UPWND_DIST_INTRST to FETCH_INTRST and FTPRNT_DIST_INTRST to FP_FETCH_INTRST
  • Revised UPWND_DIST_INTRST to FETCH_INTRST and FTPRNT_DIST_INTRST to FP_FETCH_INTRST.
v1.04November 22, 2021
  • Added CSAT3AH compile switch.
  • Added HygroVUE10 compile switch.
  • EE181 and HC2S3 compile switch removed.
  • Update to output message when zero/span coefficient is out of plausible range.
  • Update diagnostic table to match open-path EasyFlux code.
  • Position qualifiers for multiple sensors updated to match H_V_R naming convention.
  • CS616 and NRLITE compile switches removed.
  • CPEC300 compile switch removed.
  • SOIL_HT_FLUX is no longer a constant.
  • Net radiometer power control added for low-power protection.
  • Heater control for SN500SS fixed and is now properly working.
  • VOLT naming convention added for CPI expansion modules.
v1.03August 5, 2019
  • Revised as a universal program for CSI CPEC systems, being compatible with CPEC300, CPEC306, and CPEC310.
  • Added the supporting functionalities for heating and ventilation accessories (CNF4) for CNR4.
  • LI-190 and LI-200 sensor compatibility removed and replaced with CS310 and CS320. Please contact Campbell Scientific if you need code compatible with removed sensors.
  • The design of soil heat flux measurements was optimized. Now, this program can support three replications of HFP01/HFP01SC, CS655, and optional TCAV. The default depth for CS655 was revised to 8 cm for its measurement diameter of 16 cm. As a result, the default depth of HFP01/HFP01SC was revised to 16 cm and the distribution of four probes in one TVAV is also recommended.
  • Constant declarations in ConstTable are more specified for Boolean (TRUE/FALSE) and Long data types. Also for constants outside ConsTable.
  • SN500 4-way net radiometer sensor compatibility added.
  • Days of MicrSD to store more data has been more accurately estimated, which is preferred by EasyFlux_web.
  • Added the supporting functionalities for heating of the NR01.
  • Optimized the use of GPS for more accurate determination of geographic coordination data.
  • Prioritized EC155 power-off over EC100 reset while system voltage fluctuates down to the low threshold for the system to run.
v1.02April 2, 2018
  • This version corrects the compile error that the previous version had with the GPS instruction.
v1.01April 10, 2017
  • The time to power fans and heater is no longer recorded for both simultaneously while only one is on.
  • In V1.00, EC100 could be endlessly reconfigured when running at 20 Hz. This has been corrected in V1.01.
  • Sensor wire colors have been updated to match current color scheme for all sensors used in a CPEC system.
  • Updated the soil moisture corrections applied to data collected using a CS650/CS655. Temperature corrections of volumetric soil moisture values less than 5% will no longer be unnecessarily applied.
