S2-P05: Crop Phenology Monitoring

Categories: Crop Monitoring

Crop phenology monitoring services aim at:

- assessing the crop growth behavior by comparing the actual vegetation index (NDVI or LAI) with the expected behavior based on crop calendar (AFRICRS-S2-P04) and reference phenology for crops present in the area of interest or previous year crop phenology parameters;

- assessing spatio-temporal variability in cropping fields; and

- detecting any change in the phenology of the crop by comparing the most recent phenology parameters extracted by using the satellite image time series with the reference calendar, or the previous year phenology.

Crop Phenology Monitoring

This service aims at assessing the stability of the phenology cycles through the years. The product consists in seven different bands: 1) day of the year of the starting season (DOY_SOS); 2) day of the year of the ending season (DOY_EOS); 3) day of the year corresponding to the canopy maximum development (DOY_MAX) ; 4) day of the year of the maximum growing rate (DOY_G) ; 5) day of the year of the maximum degrowing rate (senescence period) (DOY_S) ; 6) value of the NDVI corresponding to the DOY_MAX; 7) growth difference in days with respect to the aspected phenology cycle.

Crop Phenology Assessment

The phenology assessment service, based on FAO WaPOR products, provides a six-bands raster output, in geotiff format. Each band contains information about the Start of Season (SOS), the Maximum of Season (MOS) and the End of Season (EOS), with a maximum of 2 growing seasons annually. The pixel values are expressed in dekad numbers and covers three calendar years with the target year in the middle (1-36 for the first year, 37-72 for the target year, 73-108 for the next year). "No season" pixel are identified with a value of 251.
