This dataset compromises eight flight lines which were acquired on 17th June 2006 using an Itres Instruments Compact Airborne Spectrographic Imager (CASI-3) as part of the Network for Calibration and Validation of Earth Observation data (NCAVEO) 2006 Field Campaign. The instrument was onboard a Cessna 404 aircraft operated by the UK Environment Agency (EA) and was operated in hyperspectral mode, with 32 spectral bands and a nominal ground resolution of 1m. The Environment Agency identified a possible spectral shift problem in the CASI-3 instrument during June 2006. The problem was corrected but it is still unknown how much the spectral shift occurred during data collection for NCAVEO. The document ‘CASI3 Wavelength correction for NCAVEO.pdf’ in further documentation provides further details. EasGeo software is also stored in the EasGeo folder in the directory as easgeo.sav, as well as documentation with further details on the data.

Reflectance data were acquired from a fixed tripod near the north-east corner of a concrete calibration site at the Chilbolton Facility for Atmospheric and Radio Research (CFARR), as part of the Network for Calibration and Validation of Earth Observation data (NCAVEO) 2006 Field Campaign. The data was collected on the 17th June 2006 using a single beam GER3700 spectroradiometer. The nominal field-of view of the instrument was 3°, and it was mounted 1 metre above the surface.

Leaf Area Index (LAI) measurements were collected using a Delta-T SunScan as part of the Network for Calibration and Validation of Earth Observation data (NCAVEO) 2006 Field Campaign. Data were collected from the following experiment fields: Rickyard (winter wheat), Fairpiece (winter oats) and Brockley (spring barley). The parameters required by the SunData program were set as follows: • Leaf Angle Distribution Parameter = 1.0 • Leaf Absorption Parameter = 0.85 Five sample points were located within tramlines in each field and their position determined using dGPS. Five 10 metre long transects were set-up, centred on each of these points and marked with coloured flags, marking the longitudinal extent of each Elementary Sampling Unit (ESU). The ‘width’ of the area sampled within the crop was determined by the reach of the instrument, around 1 metre. The geographic co-ordinates in the data file have been calculated to allow for the offset of sample measurements from the tramlines, and these should be taken as the definitive locations of the individual samples. SunScan measurements were made every metre along a 30 m transect, the central 10 m length of which coincided with the area between the coloured flags. Each of the extended ESUs was sampled in the same order in each field: Red, Green, Blue, Yellow, White flag, following a path along the tramlines shown in Figure 1. This gave a total of 165 LAI measurements per field. The geographic co-ordinates of each measurement were recorded and represented alongside the measured variables.

The Network for Calibration (cal) and Validation (val) of Earth Observation data NCAVEO organised a cal-val field experiment at Chilbolton in June 2006. The aim is to undertake a validation exercise based on the protocols and methods developed by the Validation of LAnd European Remote sensing Instruments (VALERI) project, but modified as necessary for UK conditions. The experiment is a scoping exercise for the establishment of one or more VALERI sites in the UK as well as an opportunity to learn and share best practice amongst NCAVEO partners and the wider community.

This dataset contains Aerosol Optical Thickness (AOT) data, collected at Chilbolton Facility for Atmospheric and Radio Research as part of the Network for Calibration and Validation of EO data (NCAVEO) 2006 Field Campaign. Measurements were taken every 15 minutes using a Cimel CE318-2™ sun photometer, which is part of AERONET.
