title: NWP model dataset used in "Urban multi-season sensible heat fluxes from multiple large aperture scintillometry paths: variability and operational numerical weather prediction skill"

description: These data are used in Chapter 3, “Urban multi-season sensible heat fluxes from multiple large aperture scintillometry paths: variability and operational numerical weather prediction skill” in the University of Reading thesis "Urban surface-atmosphere exchanges: scintillometry observations and NWP evaluation" submitted by Beth Saunders, 2024.

The NWP (Met Office UKV model) dataset consists of 109 days across 2016-2018. Some of the experimental setup is also described 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. File names and subdirectories are named in the format year + day of year (DOY).

The UKV data for the IOP days are from the operational runs, initialised at 21:00 UTC, with model output analysed from 00:00 UTC the following day for the period when observations are available. The operational UKV’s diagnostics output is on the hour.

Filenames are presented in the following example format:

MOUKV_FC2016050121Z_m01s00i002_LON_BCT.nc

This example would be from the UKV model (‘MOUKV’), from a run initialising at 2100 UTC on the 1st May 2016 (FC2016050121Z) for the variable ‘U component of wind’ (identified by the stash code ‘m01s00i002’), with 3 by 3 grid boxes overlaying the ‘BCT’ site as described by Saunders et al. 2024 (‘LON_BCT’).
