In 2018, with scholarship funds from Bell-MTS, we began the TGAS-MAN Camera initiative. We use images captured by the TGAS-MAN camera to remotely determine (1) crop phenological development (i.e. growth stage) using the BBCH-scale and (2) crop heights or snow pack depth in winter so we know when to adjust the gas intake height on each micrometeorology tower. The camera is programmed to take a photo every hour from 8 am to 8 pm; these are automatically uploaded to our server.
The camera is currently mounted on the central weather station and faces southeast towards the micrometeorology station in Plot 3. Included in the field of view is a high contrast post used to estimate crop height; each segment is approximately 30 cm (1 ft). The most recent image is displayed below.

2019 Growing Season – Oats
TGAS-MAN was seeded with oats on May 13, 2019. It is the first time oats have been included in the TGAS-MAN crop rotation, and marks the beginning of Phase 2 which aims to resolve significant gaps in understanding N2O emissions from the increasingly popular practice of cover cropping.
