Karst caves, a global exchanger of carbon dioxide

Description

Data from the Sloup-Šošůvka Caves (Moravian Karst)

Steps to reproduce

CO2 measurements were performed by ALMEMO 2290-4 V5 or 2590-4AS data loggers with 2-beam infrared sensors FVA600CO2H (measuring range from 0 to 10,000 ppmv, accuracy ± 100 ppmv + 3 % of the measured value) or FYAD00CO2B10 with automatic atmospheric pressure compensation (measuring range from 0 to 10,000 ppmv and accuracy ± 100 ppmv + 5 % of the measured value), respectively. All data in the Rieger Hall were logged using ALMEMO 2590-4AS datalogger with external Ahlborn sensors: CO2 sensor FYAD00CO2B10 (see above), integrated temperature (NTC, type N) / relative humidity (capacity) sensor FH A646-E1 (measuring range -20 to +60 °C and 0 to 100 %, accuracy ±0.1 °C and ±2 % of the measured value), and barometric pressure sensor FDA612-SA (measuring range 700 to 1050 mb, accuracy ±0.5 % of the measured value). Selected external data such as barometric pressure (recalculated to sea level), Pext, external temperature, T(ext), temperature near the surface of the ground, T(ground), soil temperatures, T(soil1) and T(soil2), precipitations, PR, global radiation, GR, and soil moisture, SM, were taken from the weather station Macocha (16.73022 E, 49.37215 N, 489 m a.s.l.). It is located 4 km SSW of S-SC (468 m a.s.l.).
