This data package contains 15-minute data from the Lake Hoare Meteorological Station (HOEM), located in Taylor Valley. Meteorological data are collected year-round at each of MCM LTER stations. Data are manually downloaded from the meteorological stations during the austral summer. Raw 15 minute data (Level 0) is processed and provided as Level 1 data on the MCM LTER website. Field notes, sensor information, processing procedures, QA/QC, and metadata is provided in the Meteorological Post Processing Documentation and Task Lists for each field season at the following address: https://mcm.lternet.edu/meteorological-task-lists  Name: Krista F.

Three soil probes, 0, 5 and 10 cm below the surface were added to the datalogger on Dec 29, 2002.   An ultraviolet radiometer (Kipp & Zonen CUV5 Total UV Radiometer) was installed at the Lake Hoare Met Station (HOEM) with an independent power supply and datalogger in 2015. The station is visited during the austral summer at the same time as the annual visit to HOEM. The sensor measures total UV irradiance, which is combined UVA and UVB irradiance. The values reported include minimum, maximum, and average UV in units of watts per meter squared (W m-2).   Metadata Access Constraints: none Metadata Use Constraints: none annually McMurdo Dry Valleys LTER http://mcmlter.org/ pointOfContact
