SWOT-compliant GRDC river flow dataset for the estimation of Flow-Duration Curves

This repository hosts the data used in the manuscript "Potential legacy of SWOT mission for the estimation of Flow-Duration Curves” by Alessio Domeneghetti, Serena Ceola, Alessio Pugliese, Simone Persiano, Irene Palazzoli, Attilio Castellarin, Alberto Marinelli, Armando Brath The study investigates the potential of the Surface Water and Ocean Topography (SWOT) mission for the estimation of Flow-Duration Curves (FDCs) globally. SWOT-like river flow data is derived from the Global Runoff Data Centre (GRDC) dataset by selecting river gauging stations with a cross section wider than 100 m and with more than 10-year long daily river flow time series. Overall, 1200 river gauging stations are considered, from which 24 alternative SWOT-like river flow datasets can be derived by assuming different satellite revisiting times, biases and random errors, as detailed in the manuscript. The dataset includes detailed features on the selected 1200 river gauging stations. GRDC river flow daily time series for each station is provided as .csv. A .shp file provides the geographical location of each GRDC gauging station, including GRDC number, river, gauging station municipality, country, latitude and longitude, contributing area, altitude and Köppen-Geiger climate classification.本仓库收录了Alessio Domeneghetti、Serena Ceola、Alessio Pugliese、Simone Persiano、Irene Palazzoli、Attilio Castellarin、Alberto Marinelli、Armando Brath合著的论文《水面与海洋地形（Surface Water and Ocean Topography, SWOT）任务对流量历时曲线（Flow-Duration Curves, FDC）估算的潜在遗留价值》（英文原标题："Potential legacy of SWOT mission for the estimation of Flow-Duration Curves"）所使用的数据集。 本研究旨在全球范围内评估SWOT任务在流量历时曲线（FDC）估算方面的应用潜力。类SWOT河流流量数据源自全球径流数据中心（Global Runoff Data Centre, GRDC）数据集，筛选标准为河道断面宽度大于100米、且拥有超过10年逐日河流流量时间序列的河道监测站。本次研究共纳入1200处河道监测站，基于不同的卫星重访周期、系统偏差与随机误差假设，可从该数据集衍生出24套类SWOT河流流量数据集，具体细节详见论文正文。 本数据集包含上述1200处河道监测站的详细属性信息。各监测站的GRDC逐日河流流量时间序列以.csv格式存储。另有一份.shp格式文件，收录了各GRDC监测站的地理位置信息，具体包括GRDC编号、所属河流、监测站所在城镇、国家、经纬度、汇水面积、海拔高度以及柯本-盖格气候分类（Köppen-Geiger climate classification）。
