Observational dataset used in "Methodology to evaluate numerical weather predictions using large aperture scintillometry sensible heat fluxes: demonstration in London"

These data are used in Saunders et. al 2024: “Methodology to evaluate numerical weather predictions using large aperture scintillometry sensible heat fluxes: demonstration in London”, DOI: https://doi.org/10.1002/qj.4837 Observational datasets from two days (2nd May 2016, day of year (DOY) 123, and 5th May 2016, DOY 126) used in Saunders et al. 2024. Day cases are separated by folder named in the format year + DOY. AWS processed: Processed and quality-control checked data from a Davis Vantage Pro Plus located in the city of London (Saunders et al. 2024). CNR4 processed: Processed and quality-control checked data from a Kipp & Zonen CNR4 radiometer in the city of London (Saunders et al. 2024). LAS raw: Raw data from a single beam Kipp and Zonen MKII LAS (850 nm wavelength) sensor defined as the scintillometer path ‘BCT-IMU’ (Saunders et al. 2024) located between the City of London and Islington. LAS source areas: Source areas for the scintillometer path ‘BCT-IMU’. Data are derived using the methodology as described by Saunders et al. 2024 (see Fig. 2), and were written using the ‘scintools’ python code (10.5281/zenodo.7434074). Digital surface models used for these cases are also included as part of the ‘scintools’ zenodo repository. Source areas for the specific case study days used in Saunders et al. 2024 are processed using the python code ‘scint_fp’ (included in 10.5281/zenodo.7434153) using automatic weather station data included here (in the directory AWS processed). csv files included in each subdirectory of ‘LAS_Source_Areas’ are the inputs given to ‘scint_fp’. Files in the ‘10_mins’ subdirectory are source areas every at 10 minutes. Files in the ‘hourly’ subdirectory are source areas calculated every 60 minutes. The end of each file name indicates the time period (time ending) of which the source area applies. Files in the ‘SA_constant’ subdirectory are source areas with roughness parameters calculated and held constant along the path (only used for sensitivity tests, see Fig.5 and Fig. SM.5 of Saunders et al. 2024). LAS processed: Processed data from the scintillometer path ‘BCT-IMU’. Data were derived using the methodology as described by Saunders et al. 2024 (see Fig. 3), and written using the ‘scint_flux’ python code (10.5281/zenodo.7434143) and using scintillometer source areas derived from the ‘scintools’ python code (10.5281/zenodo.7434074). Files ending with PERIOD_VAR_## refer to the averaging period performed on the LAS raw data as number in minutes (where ## is 1, 2, 3, 5, 10, 15, 20, 30, and 60 minutes). Files with a name including ‘sa10min’ use source areas calculated every 10 minutes. Otherwise, data are calculated source areas calculated every 60 minutes.
