TGAS-MAN Camera

In 2018, with scholarship funds from the Bell-MTS Innovations in Agriculture Program, we began the TGASCam initiative. We use true-colour images captured by a stationary 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 also captures Normalized Difference Vegetation Index (NDVI) images.

The camera is currently mounted on the central weather station and faces southeast towards the micrometeorology station in Plot 3. It is programmed to take a photo every hour from 8 am to 8 pm; these are automatically uploaded to our server. Included in the field of view during the growing period 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.

The TGAS-MAN Camera takes 13 photos a day, each capturing field activity for only a fraction of a second. The likelihood that one of those images would include the Manitoba Field Sasquatch is infinitesimal! However, the figure in this picture is not blurry, leading us to believe it is probably Katie, the TGAS-MAN technician, checking out Tower 3.

A beautiful view of a TGAS micrometeorological station, including a few optical phenomena called “halos”, which are created by sunlight interacting with ice crystals suspended in the atmosphere. To the left of the sun, you can see a bright parahelion (aka sun dog) with a partial parhelic circle extending outward (bright horizontal line) and part of a 22° halo extending above and below the sundog (Jan 18, 2021 at 9am).

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 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. Read more about Phase 2.
