Meteorological data for the Siksik catchment, North West Territories, Canada for 2013 and 2014

Data comprise meteorological measurements (mean, minimum and maximum daily air temperature, minimum and maximum daily relative humidity, wind speed (kilometres per second at 10metres height), dew point temperature, estimated actual vapour pressure, precipitation, estimated surface resistance, estimated albedo and estimated Potential evapotranspiration (PET)) for the Siksik catchment, North West Territories, Canada for 2013 and 2014.

The data were collected under Project HYDRA, a NERC funded UK research project linking Heriot Watt University, the Universities of Durham, Aberdeen and Stirling, and the Centre for Ecology & Hydrology (CEH), Edinburgh. Project HYDRA is part of the UK Arctic Research Programme. Project HYDRA studies sites in Arctic Canada to investigate the biological, chemical and physical controls on the release of greenhouse gases from permafrost into melt water and to the atmosphere and how these emissions will influence global warming.

本数据集涵盖加拿大西北地区锡西克流域（Siksik catchment）2013年与2014年的气象观测数据，具体包括每日平均、最低及最高气温，每日最低与最高相对湿度，10米高度处的风速（单位：千米每秒）、露点温度、估算实际蒸气压、降水量、估算表面阻力、估算反照率以及估算潜在蒸散量（Potential evapotranspiration, PET）。
该数据由HYDRA项目采集所得。此项目为英国自然环境研究委员会（Natural Environment Research Council, NERC）资助的英国研究项目，合作机构包括赫瑞-瓦特大学、杜伦大学、阿伯丁大学、斯特灵大学以及爱丁堡生态与水文中心（Centre for Ecology & Hydrology, CEH）。HYDRA项目隶属于英国北极研究计划，其研究以加拿大北极地区的多个站点为对象，旨在探究永久冻土区温室气体向融水及大气释放的生物、化学与物理控制机制，以及此类排放将如何影响全球变暖。
