HydroPenIndia: A catalogue of streamflow metrics, meteorological time series and catchment attributes of Peninsular India

HydroPenIndia, a catalogue of streamflow metrics, hydro-meteorological time series and landscape attributes of 204 catchments of Peninsular India is introduced. This catalogue consists of daily hydro-meteorological time series (rainfall, soil moisture, potential evapotranspiration, actual evapotranspiration, maximum temperature, minimum temperature, longwave radiation, shortwave radiation, wind speed and humidity) for a period of 36 years from 1980-2015. The time series of 26 streamflow metrics, 13 topographic metrics, 12 climate indices, 15 hydrologic signatures, 8 land cover descriptors, 6 geologic characteristics, 6 soil characteristics (see table 8) and 13 human intervention indices are also included in this dataset. HydroPenIndia is an initiative to encourage hydrologists to advance knowledge of hydrological processes by contributing to fundamental research questions on Indian catchments. Free availability of the dataset will provide access to global users to represent India in large-sample hydrology studies. HydroPenIndia is derived from multiple databases to help researchers start their research without wasting time on collecting and processing datasets. This catalogue will motivate researchers to solve pertinent issues related to water management, quantification and risk assessment of hydrologic extremes, unravelling regional scale hydrologic functioning and climate change impact assessment over Peninsular India.

本文介绍了HydroPenIndia，一款涵盖印度半岛204个集水区径流指标、水文气象时间序列与景观属性的数据集汇编。本汇编包含1980-2015年共36年的日尺度水文气象时间序列数据，具体涵盖降雨量、土壤湿度、潜在蒸散发、实际蒸散发、最高气温、最低气温、长波辐射、短波辐射、风速与湿度等要素。此外，该数据集汇编还收录了26项径流指标、13项地形指标、12项气候指数、15项水文特征值、8项土地覆盖描述符、6项地质特征、6项土壤特征（详见表8）以及13项人类干预指数。HydroPenIndia旨在推动水文学者围绕印度集水区的基础研究问题展开探索，深化对水文过程的认知。该数据集汇编免费对外开放，可为全球用户在大样本水文学研究中表征印度区域水文特征提供数据支撑。HydroPenIndia整合自多类数据库，可帮助研究者免去收集与预处理数据集的耗时工作，直接启动相关研究。本数据集汇编将激励研究者解决印度半岛地区的诸多核心议题，包括水资源管理、水文极端事件量化与风险评估、揭示区域尺度水文运行机制以及气候变化影响评估等。
