资源简介：
As part of the HEGS project, an attempt was made at reconstructing flood and heavy precipitation probabilities for thousands of stations worldwide and for the period 1836-2015. This repository contains the precipitation/streamflow data underlying this reconstruction (https://vimeo.com/802751683), and the reconstruction itself. Details can be found in this publication.
Data
Seasonal maxima of daily precipitation or streamflow. One file for each season, with the following columns:
"var": variable 'Rx1day' (heavy precipitation) or 'Qx' (flood).
"year": year. For the DJF season, year e.g. 1998 spans from December 1998 to February 1999.
"siteID": ID of the site, as used in the original HadEX2/HadEX3 and GSIM datasets.
"lon": longitude.
"lat": latitude.
"value": seasonal maximum value, in mm (precipitation) or m3.s-1 (streamflow).
"returnPeriod": return period T associated with the value above.
"nonExceedanceProb": non-exceedance probability associated with the return period (p=1-1/T).
Reconstructions
Probability of exceeding T-year events and predictive quantiles, estimated at all stations and for the period 1836-2015. One file for each season, with the following columns:
"var": variable 'Rx1day' (heavy precipitation) or 'Qx' (flood).
"year": year. For the DJF season, year e.g. 1998 spans from December 1998 to February 1999.
"siteID": ID of the site, as used in the original HadEX2/HadEX3 and GSIM datasets.
"lon": longitude.
"lat": latitude.
"Pr[exceeding the 2-year event]": estimated probability of exceeding the 2-year event at this site during this season.
"Pr[exceeding the 10-year event]": estimated probability of exceeding the 10-year event at this site during this season.
"Pr[exceeding the 100-year event]": estimated probability of exceeding the 100-year event at this site during this season.
"q5": 5%-quantile of the predictive distribution at this site during this season.
"q10": 10%-quantile of the predictive distribution at this site during this season.
"q25": 25%-quantile of the predictive distribution at this site during this season.
"q50": 50%-quantile of the predictive distribution at this site during this season.
"q75": 75%-quantile of the predictive distribution at this site during this season.
"q90": 90%-quantile of the predictive distribution at this site during this season.
"q95": 95%-quantile of the predictive distribution at this site during this season.
