PARAMETERS & UNITS: Digital Numbers (DN)

DESCRIPTION: 
Collection of quality filtered phenocamera RGB images every hour from 10 a.m. to 2 p.m. 
The phenocamera pointed to an experimental arable land, composed by a perennial cropland system. For detailed information about the crop system and rotation cycle, refer to this document (PID: https://hdl.handle.net/11676.1/_Eu76kOwEaReq39cluHGHGdG)

SENSOR DESCRIPTION:
Data acquired with Mobotix M25 RGB phenology camera, with wide field of view (FOV) angle of 60 degrees. Images stored in JPG format.  

DATA ACQUISITION
The original images were acquired with a phenology camera on an observation mast, at a height of 10 m above ground, looking north (12 degrees) and an off-nadir angle of 58 degrees. The phenocamera acquired images from 6 a.m. to 7 p.m. every hour. The phenocamera operates all year long. 
The area surveyed by the phenocamera projects a footprint on the ground, the centroid of which is defined by the following coordinate (latitude, longitude in GCS WGS84, decimal degrees): 55.669186, 13.110360. 

PROCESSING METHODS:
No image processing applied at this stage. However, low quality images were filtered out manually from the original image collection. Low quality refers to images that contain sun glare, rain droplets, fog, or shadows, or represent low-light or blurry conditions.
