Turbulent sensible and latent heat fluxes, net all-wave radiation flux and CO2 flux are monitored
by these two Flux Towers, which are installed in the city of Heraklion and representative of a wide
area around the Sensors. Both are equipped with IRGASON Integrated CO2/H2O Open-Path Gas Analysers,
3D Sonic Anemometers and CNR1/CNR4 Net Radiometers. The first one (HECKOR) operates since 2016 at
the city center and the second one (HECMAS) operates since 2021 at a residential area in Heraklion,
while their real time measurements (temperature, wind and air pressure, radiation, fluxes) are
available from a dedicated Web Portal providing measurement charts.
As of 2023, both flux towers have become integral parts of the
ICOS
(Integrated Carbon Observation System) flux towers network.
This integration underscores the exceptional quality of measurements and the utilization of cutting-edge techniques in the acquisition of data.
