Synthetic Aperture Radar (SAR) for Agriculture
Field-linked. Cost-effective. Analysis-Ready. Fast and Easy to access. Available as part of Agrimetrics Standard Data Subscription.
Benefits of SAR via Agrimetrics
We have created a hub of pre-processed Synthetic Aperture Radar (SAR) from the European Space Agency's Sentinel-1 satellite constellation. Accessing pre-processed SAR data offers a number of significant time and cost savings over the raw data.
Available at field level
SAR images from ESA cover a 250x200km area. We enable SAR data to be purchased for an individual UK field.
Available instantly
The four years of UK SAR data we obtained from the European Space Agency (ESA) would take many months or years to process. We reduce this to minutes.
Lower data storage costs
Storing SAR data is expensive, for the UK it would cost >£10k a year. Through Agrimetrics, you obtain only the analysis-ready data you need, saving substantial costs.
Download sample data for the research farms of Rothamsted Research and The University of Reading, two of our founding partners, plus 18 randomly chosen fields throughout England and Wales,
Pre-linked to other field data
SAR data accessed through Agrimetrics comes pre-linked to other data within the Data Marketplace, and can be quickly analysed at the field level. The linked-data technologies underpinning the Data Marketplace also makes connecting third-party data faster and simpler.
Weather data
A range of historic and forecasted weather data available for every field in the UK
Optical satellite data
15 crop analytics supplied by Airbus, including Leaf Area Index (LAI), NDVI, and Leaf Water Content
Field & cropping data
The history of crops growing in UK fields, plus other field-level data, including soil, cultivation, and biodiversity indicators
Key Parameters
Agrimetrics have derived two key parameters, alongside other supporting metrics and metadata, from the Synthetic-Aperture Radar (SAR) data. These are calibrated and corrected for geometrical and terrain effects before attributing to every field in the UK from January 2017 to present, at a six days revisit time.
Sigma0
Also known as the Scattering Coefficient, this typically represents the strength of radar signals reflected by a distributed target. It is a normalised, dimensionless number, from an area of one square meter. Sigma0 is defined with respect to the nominally horizontal plane and in general has a significant variation with incidence angle, wavelength, and polarisation (in VV and VH in our case), as well as with properties of the scattering surface.
Gamma0
This is derived from Sigma0 by normalising over the cosine of the incidence angle to take into account the topographic effects of the terrain.
