Description
The data package provides processed sensible and latent heat fluxes, at 30-minute temporal resolution, of 3 dual-wavelength scintillometer systems at two locations: one system over the city centre of Amsterdam (part of the MAQ Amsterdam urban supersite) and two systems at the Cabauw Experimental Site for Atmospheric Research (CESAR), a long-path system operated by KNMI and a short-path system operated by WUR.
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 the 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) is then used to convert structure parameter data into turbulent fluxes.
