The installed instrumentation allows CO2 flux measurements from soil (emission and absorption/uptake) by non steady state closed dynamic accumulation Chambers.
\nThe aim is to understand if the NEE (Net Ecosystem Exchange) is increasing or decreasing and which parameters most affect this important index. More over, the NEE parameter is extremely useful in climate models.
\nIn particular chamber n.1 is a dark chamber and measures the ecosystem respiration while chamber n.2 is a transparent chamber and measures the NEE. The difference between the flux measured by chamber n.2 and that measured by chamber n.1 allows to calculate the GPP (Gross Primary Production).
\nThis dataset presents data collected by chamber 1 (Camera_1_2025.xlsx) and chamber 2 (Camera_2_2025.xlsx) every hour.
\nThe dataset includes the Net Ecosystem Exchange (NEE), Ecosystem Respiration (ER), atmospheric pressure inside the chamber, soil temperature and soil humidity next to the chamber. It is also available the R2 of the regression line of the CO2 concentration versus time, of each chamber. For transparent chamber H2O flux, number of micromoles of photons striking 1 m² per second and R2 of the regression line of the H2O concentration versus time, are also available.
\nThe \"Camera_1_2025.xlsx\" file contains the following fields:
\nDate: Date and time [DD/MM/YYYY hh:mm:ss]
\nCO2 flux[3] [moles/m^2/day]: Ecosystem Respiration (ER)
\nCO2 errq[3]: R2 of the regression line of the CO2 concentration versus time
\nSoil W.[3] [%]: soil humidity next to the chamber
\nSoil T.[3] [°C]: soil temperature and soil humidity next to the chamber
\nBarP[3] [hPa]: atmospheric pressure inside the chamber
\nThe \"Camera_2_2025.xlsx\" file contains the following fields:
\nDate: Date and time [DD/MM/YYYY hh:mm:ss]
\nCO2 flux[4] [moles/m^2/day]: Ecosystem Respiration (ER)
\nCO2 errq[4]: R2 of the regression line of the CO2 concentration versus time
\nH2O flux[4] [moles/m^2/day]: water flux
\nH2O errq[4]: R2 of the regression line of the H2O concentration versus time
\nPAR[4] [µmoles/m^2/s]: numero di micromoli di fotoni che colpiscono 1 m² ogni secondo.
\nSoil W.[4] [%]: soil humidity next to the chamber
\nSoil T.[4] [°C]: soil temperature and soil humidity next to the chamber
\nBarP[4] [hPa]: atmospheric pressure inside the chamber
