Description

This project operates and maintains ground-based Fabry-Perot spectrometers at McMurdo and South Pole Stations. The instruments measure mesospheric and thermospheric neutral winds and temperatures at heights of around 87 km, 120 km, and 240 km. Data collected informs both large-scale changes in mean flow and small-scale local perturbations, independently resolves impacts due to forcing from above and from below and contributes to studies utilizing data from other types of observing systems located in Antarctica.

Field Season Overview

One participant will deploy to service the equipment this season. The objective will be to perform urgent maintenance plus minor upgrades. This will involve work on the instruments inside their respective labs at Arrival Heights near McMurdo Station and in the ARO building at South Pole Station. No off-station fieldwork is required. An onsite research associates will provide monitoring, troubleshooting, and the collection and forwarding of data as needed throughout the year.
