An automated weather station operates at Cape Adare (-71.30492, 170.23256). The station was established in 2014 and continues to transmit live data. Data are logged every 30 minutes. Parameters: - Air Temperature (C) - Relative Humidity (%) - Solar Radiation (W/m2) - PAR (uE) - Wind Speed (m/s) - Wind Gust (m/s) - Wind Direction (true bearing degrees) GET DATA: adminteam@antarcticanz.govt.nz

This metadata record represents the code and data used for the first application of WRF-Hydro/Glacier in the McMurdo Dry Valleys (Commonwealth Glacier), which as a fully distributed hydrological model has the capability to resolve the streams from the glaciers to the bare land that surround them. We applied a glacier and hydrology model in the McMurdo Dry Valleys (MDV) to model the start and duration of melt over a summer in this extreme polar desert. To do so, we found it necessary to prevent the drainage of melt into ice and optimize the albedo scheme. We show that simulating albedo (for the first time in the MDV) is critical to modelling the feedbacks of albedo, snowfall and melt in the region. This is a first step towards more complex spatial modelling of melt and streamflow.

Automated weather stations were installed to measure local scale weather conditions at Miers Valley, Miers Ridge, Commonwealth Glacier, Cape Christie, and Haystack Mountain. Miers Valley, Miers Ridge and Haystack Mountain stations have been operating since early 2021, Haystack, Commonwealth Glacier and Cape Christie were installed in December 2021, 2022, and 2023, respectively. Data are available on request in NetCDF. Parameters: - average air temperature (C) - average relative humidity (%) - average short wave in (W/m2) - average pressure (hPa) - wind speed (ms-1) - wind direction (true bearing degrees) - wind standard deviation Coordinates: - Miers Valley (-78.09805, 163.794283) - Miers Ridge (-78.123205, 163.863319) - Commonwealth Glacier (-77.563987, 163.281064) - Cape Christie (-72.29722222, 169.9847222) - Haystack Mountain (-77.05, 162.585) GET DATA: marwan.katurji@canterbury.ac.nz
