Illilouette Creek Basin Weather Stations

This data is part of a project studying the effects of wildfire on the Illilouette Creek Basin, a watershed within Yosemite National Park. Three temporary weather stations were installed under distinct types of vegetation cover (A is forested, B is shrub-dominated, and C is in a wetland). Each station measures air temperature, relative humidity, rainfall (the rain gage is not heated, so only the portion of snowfall that melts within the gage is measured), wind speed and direction, solar radiation, and both soil moisture and temperature at three depths. These measurements are recorded every 10 minutes, beginning in the summer of 2015. Snow depth was estimated at each station four times per day during each winter using time lapse imagery. In addition, HOBO temperature and relative humidity sensors were attached to nearby trees in order to provide backup data and to capture temperatures above the snowpack during high snow years. The stations are located within an area that burned most recently in 2004 and 2017. Metadata files are included within each individual resource.

本数据集归属于一项探究野火对伊利卢特特溪流域（Illilouette Creek Basin）影响的研究项目，该流域为约塞米蒂国家公园（Yosemite National Park）内的一片集水区。研究团队在三种不同植被覆盖类型下布设了三台临时气象站：A站设于林地，B站设于以灌木为主的生境，C站设于湿地生境。每台站点均监测气温、相对湿度、降雨量（雨量计未加热，因此仅能计量在雨量计内部融化的降雪部分）、风速与风向、太阳辐射，以及三个深度层级的土壤湿度与土壤温度。所有监测数据每10分钟记录一次，监测工作始于2015年夏季。在每个冬季，研究人员每日通过延时影像四次估算各站点的积雪深度。此外，团队还在周边树木上安装了HOBO温湿度传感器，以提供备份数据并采集多雪年份积雪层上方的气温。所有站点所在区域最近一次野火活动发生于2004年与2017年。每个独立资源包均附带元数据（metadata）文件。
