Phenocam data from El Mogor, Baja California, Mexico, 2016

Listed in DataCite

This dataset provides daily observations of greenness index (I g ), from three wildlife cameras (M-550, Moultrie) for the year of 2016, at the study site of El Mogor, Baja California, Mexico (32.03017 N, 116.604219, 406 m asl).

Description

Vegetation at El Mogor is a mixture of chaparral and less-sclerophyllous species, including Ornithostaphylos oppositifolia , Eriogonum fasciculatum , Adenostoma fasciculatum , Xylococcus bicolor and Malosma laurina .

The study site was burned in 1988 and has been recovering since then. El Mogor is a MexFlux site (MX-EMg; ameriflux.lbl.gov/sites/siteinfo/MX-EMg), equiped with an eddy covariance tower. The cameras were static, oriented in parallel with the soil surface, facing north, at ~1.5 m aboveground.

Each camera works with eight AA-batteries, and are equipped with 16 GB SD-memory cards. Each camera took photographs in 30-minute intervals between 4:00 and 19:30 PST in a daily manner, but I g was estimated using only photographs taken between 11:00 and 15:00 PST. Resolution of the photographs is 2304x1728 pixels.

The image analysis included the definition of the region of the interest (ROI). From each pixel within the ROIs, the digital signature of the intensity of red, green, and blue were extracted and averaged on a per-day basis. Each digital signature has values of 0 to 255.

To analyze the photographs, we used the Matlab-based PhenoCam GUI software, available from the PhenoCam Network (phenocam.sr.unh.edu/webcam/tools/). The greenness index is estimated as [I g = Green/(Red + Green + Blue)].
