Data descriptions
-------------------

This dataset includes road weather station measurements and road surface temperature 
forecast data related to manuscript entitled "Effects of sky view factor and screening 
on road surface temperature forecast accuracy in Finland". The manuscript will be 
submitted to a scientific journal for publication. 

There is a separate ReaMe file for different data types:
ReadMe_measurements.txt for road weather station measurements
ReadMe_meps.txt for MEPS data
ReadMe_simulations.txt for road weather model output surface temperature
ReadMe_verification_results.txt for verification results
Coordinates and station IDs can be found from the file "coordinates.txt"

local_horizons.txt
-----------------------
Contains local horizon angles calculated from National Land Survey of Finland’s (NLS) 
laser scanning data 
(https://www.maanmittauslaitos.fi/en/maps-and-spatial-data/expert-users/product-descriptions/laser-scanning-data)

Column Variable
1      station id 
2      station name
3->    local horizon angels, starting from 0 degrees (north) and continuing with 1 degree steps in clockwise direction


rws_data*
-----------------
Contains road weather station measurements used in the forecast verification.

meps_forecast*
-----------------
Contains NWP forecasts produced with MEPS ((MetCoOp Ensemble Prediction System )model 
(cycle 40h1.2 2018-10-1 00Z - 2019-03-31 18Z, cycle 40h.1.2 2019-10-1 00Z - 2021-03-23 06Z,
cycle 43h2.1.1 2021-03-23 12Z - 2021-03-31 18Z). Only the control run is included.
Model runs are done as part of MetCoOp (Meteorological Co-operation on Operational Numerical Weather Prediction)
cooperation between Swedish Meteorological and Hydrological Institute, Norwegian Meteorological institute
and Finnish Meteorological Institute. More info in ReadMe_meps.txt

tsurf_model*
----------------
Contains surface temperature from road weather model simulations done
with different settings. The simulations were 3 days long but the files contain
data only from the last day that was used in the analysis. 
The runs are done with Finnish Meteorological Institutes road weather model.
For more details of the road weather model see https://doi.org/10.1002/met.1486

rmse_bias_stations*
contingency_stations*
bootstrap_rmse_bias_stations_overall.txt
---------------------
Contains bias, RMSE, number of misses and number of false alarms for simulations
and results of statistical significance tests,  more info in ReadMe_verification_results.txt
