The Amsterdam Atmospheric Monitoring Supersite (AAMS) contains an eddy covariance flux tower measuring turbulent fluxes of sensible heat, latent heat (evapotranspiration), CO2 and methane, and contains a scintillometer as well.

This collection contains monthly and annual mean fluxes between 2001-2023 for the various components of the CarbonTracker Europe data assimilation system, for the inversions performed for the GCB2024.
Prior biosphere fluxes are calculated using the SiB4 model (Haynes et al., 2019, https://doi.org/10.1029/2018MS001540). Prior ocean fluxes are taken from Jena Carboscope v2023 (Roedenbeck et al., 2013, https://doi.org/10.5194/os-9-193-2013). Imposed fire fluxes are taken from GFAS (di Giuseppe et al., 2018, https://doi.org/10.5194/acp-18-5359-2018). Imposed fossil fuel fluxes are taken from GridFED v2024.0 (Jones et al., 2021, https://doi.org/10.1038/s41597-020-00779-6).

This is a 25 years (1996-2021) observational dataset of meteorology, turbulent fluxes and net ecosystem exchange collected from the first tower at the Loobos site, the Netherlands (NL). The presented dataset contains six data streams, namely (1) the NL-Loo_BM stream including meteorological data: four-component radiation (radiation balance), air temperature and relative humidity, wind information, precipitation and throughfall, photosynthetic active radiation, bole temperature and soil heat flux), (2) the NL-Loo_Profile stream containing vertical profiles of CO₂ mole fraction, H₂O pressure, air temperature and relative humidity, (3) the NL-Loo_ST stream derived from the aforementioned two streams including total stored heat flux, H₂O and CO₂ fluxes below the canopy, (4) the NL-Loo_EC stream including EC measurements of CO₂ flux, sensible heat and latent heat fluxes, (5) the NL-Loo_Soil stream including vertical profiles of soil moisture and temperature and ground water level data, and (6) ancillary data including soil respiration, vegetation properties (i.e., tree height, stem width and dry aboveground biomass, Leaf Area Index, sap flow, needle foliage properties and the associated nutrient analysis) and ground water level. The data quality of these data streams is assured through standard operating procedures.

Since March 2025 ozone concentration and flux observations have been collected at Loobos, NL (52.166446 degN, 5.743575 degE). A fast Eddy-Correlation system measuring at 20 Hz has been installed at the top of the tower (38m), well above the forest canopy. Simultaneously, a slow Thermo Model 49C O3 Analyzer has been installed to measure ozone concentrations at a 1-minute interval. Both instruments are cross-calibrated. +

Carbon dioxide (CO2) exchange over Europe at high resolution (0.1 × 0.2∘) and in near real time (about 2 months' latency) was estimated with the CarbonTracker Europe High-Resolution (CTE-HR) system. The modelled CTE-HR CO2 fluxes matched mole fraction observations at Integrated Carbon Observation System (ICOS) sites across Europe after atmospheric transport with the Transport Model, version 5 (TM5) and the Stochastic Time-Inverted Lagrangian Transport (STILT), driven by ECMWF-IFS, and captured the magnitude and variability of measured CO2 fluxes in the city center of Amsterdam (the Netherlands). Details of this dataset is described in detail in: van der Woude et al., Near-real-time CO2 fluxes from CarbonTracker Europe for high-resolution atmospheric modeling, Earth Syst. Sci. Data, 15,, 579–605, https://doi.org/10.5194/essd-15-579-2023, 2023. +
The MicroWave Scintillometer (MWS) PRG-MWSC-160 is combined with an optical Large Aperture Scintillometer (LAS) in the near infrared spectral region to simultaneously observe sensible and latent heat fluxes. The measurements are significant for applications in radiation budget studies, weather forecasting, irrigation and water management. The OMS measurements are conducted at Cabauw site with a short parth (800m) and a long path (10km) instrumentation.The sampling frequency is 1000Hz.
WUR has processed scintillimeter raw scintillation data. The processed data include latent and heat fluxes at 30-minute interval.In addition to the turbulent flux values, the dataset contains: 1) the scintillation statistics and raw data quality flags; 2) variance data and structure parameters data, 3) ancillary data including essential meteorological data.
The data processing workflow is as follows. The raw scintillometer data were physically constrained and cleaned of spikes using an IQR-based despiking method. The resulting quality flags were kept to assist in data quality evaluation. Subsequently, a moving window was used as a high-frequency filter to separate the scintillation signal from atmospheric absorption processes. The index and the variance of index were calculated. Then the refractive index structure parameters were calculated using the WUR developed hybrid method, which is based on the Ludi et al., (2005) method combined with the Hill et al. (1980) method. The Monin-Obukhov Similarity Theory (MOST) was then used to convert structure parameter data into turbulent fluxes. +
