n Situ Data:

Climate Data

Forty-two weather stations within the JECAM site collect data daily. Parameters include rainfall, temperature, wind speed and direction, and soil water at a selected number of stations (5). The following graph shows data collected at one of the stations for rainfall and soil moisture.

Crop Type Observations

The Producer Independent Crop Estimation System (PICES) collects around 4500 visual observations of crop type with in fields (and some ancillary data) from light aircraft for the winter and summer growing season. These points comprise observations of statistically selected sample points as well as opportunistic observations between sample points while traversing the agricultural area. This data is used to estimate crop type areas.

 

Yield Measurements

At around 670 points, yield measurements are collected in situ for wheat and maize. These are used to estimate average yield for the province for the two crops.

 

Figure 2 shows the crop condition on a scale of 1 (good) to 9 (total failure) on 18 February 2015. Drought ravaged some areas of the Free State.

Plans for Next Growing Season:

We plan to maintain the current approach next year. The EO data to be ordered next year will include Sentinel-2 data when available.
