Seasonal evolution of soil and plant parameters on the agricultural Gebesee test site: a database for the set-up and validation of EO-LDAS and satellite-aided retrieval models
Ground reference data are a prerequisite for the calibration, update, and validation of retrieval models facilitating the monitoring of land parameters based on Earth Observation data. Here, we describe the acquisition of a comprehensive ground reference database which was created to test and va...

description |
Ground reference data are a prerequisite for the calibration,
update, and validation of retrieval models facilitating the monitoring of
land parameters based on Earth Observation data. Here, we describe the
acquisition of a comprehensive ground reference database which was created to
test and validate the recently developed Earth Observation Land Data
Assimilation System (EO-LDAS) and products derived from remote sensing
observations in the visible and infrared range. In situ data were collected
for seven crop types (winter barley, winter wheat, spring wheat, durum,
winter rape, potato, and sugar beet) cultivated on the agricultural Gebesee
test site, central Germany, in 2013 and 2014. The database contains
information on hyperspectral surface reflectance factors, the evolution of
biophysical and biochemical plant parameters, phenology, surface conditions,
atmospheric states, and a set of ground control points. Ground reference data
were gathered at an approximately weekly resolution and on different spatial
scales to investigate variations within and between acreages. In situ data
collected less than 1 day apart from satellite acquisitions (RapidEye,
SPOT 5, Landsat-7 and -8) with a cloud coverage ≤ 25 % are
available for 10 and 15 days in 2013 and 2014, respectively. The measurements
show that the investigated growing seasons were characterized by distinct
meteorological conditions causing interannual variations in the parameter
evolution. Here, the experimental design of the field campaigns, and methods
employed in the determination of all parameters, are described in detail.
Insights into the database are provided and potential fields of application
are discussed. The data will contribute to a further development of crop
monitoring methods based on remote sensing techniques. The database is freely
available at PANGAEA (<a href="https://doi.org/10.1594/PANGAEA.874251" target="_blank">https://doi.org/10.1594/PANGAEA.874251</a>).</p> |
