China - Shandong

Operational Implementation Plans

In Situ Data

The main variables measured and instruments we are using are shown in Table 1. All the variables were measured once a month from April to September except for the following. Yield, harvest index and crop type mapping were measured once per growing season.

 

Main variables

Instruments or processing method

Above ground dry biomass

Oven dried and weight

Yield

Oven dried and weight

Harvest index

Calculated by yield and AGB

Density/canopy height

Tape measured

Crop type field boundary

GPS record using GIS system

The biggest challenge is weather condition during the field observations. It is sunny in the morning while cloudy at noon; this may influence measurements of field spectral and FAPAR.

The shift from growing cereals to cash crops makes the field observation at all the same fields as the previous year impossible. We had to slightly change the selected fields during the field campaign.

 

Plans for the Next Growing Season:

In 2016 and the future, we will measure the same variables as in 2015.

We already submitted the acquisition plan for newly launched GF-5 geostationary satellite images with 50m resolution at daily temporal resolution.
