The reflectance spectra of the spring barley of field Brockley, near Chilbolton was collected as part of the Network for Calibration and Validation of Earth Observation data (NCAVEO) 2006 Field Campaign. This dataset compromises the data which was collected on the 15th June. Measurements were also taken on the 18th at this location, the dataset record for which is available through linked documentation. Measurements were recorded using an ASD N4406 FieldSpec Pro, measurements having been taken at 5 flags within the field. After the exclusion of noisy bands, the spectra contains 1926 bands, covering the wavelengths 350-1354 nm, 1409-1811 nm and 1952-2496 nm. For further information on the processing of the raw data please see the dataset's metadata pdf in linked documentation. Please note that all raw spectra files collected during the NCAVEO campaign with ASD N4406 have incorrect dates. The laptop computer used with the ASD had the month accidently set to JULY instead of June. The DAY of month and TIME (UTC) are correct in all cases. All other files (FSF spreadsheets and Excel/ENVI summary outputs) are marked with the correct 15-18th June 2006 dates.

Spectra measurements were collected for a patch of bare soil at the northern corner of Brockley field, near Chilbolton, to establish the field's typical soil background reflectance. The measurements were recorded on the 18th June 2006 as part of the Network for Calibration and Validation of Earth Observation (NCAVEO) 2006 Field Campaign. An ASD Fieldspec Pro Instrument (FR Unit No. 6408, NCAVEO Code N4406), owned by Newcastle University, was used with an 8° FOV foreoptic. All measurements were collected using a 1.5m extension probe from a height of ~1.35 metres above the ground, with the foreoptic positioned approximately 1.5m from the tramline, in a vertical plane unless stated otherwise. At each pair of coloured flags 11 sets of panel/target measurements were taken at approximately 1 metre intervals moving from left [01] to right [11] facing from the tramline towards the crop. 30 samples were averaged per data point. Times recorded are UTC (GPS time).

A Hemispherical Camera (Nikon Coolpix 995) was used to take photographs at sites Harewood Forest, Rickyard and Fairpiece, near Chilbolton, as part of the Network for Calibration and Validation in Earth Observation 2006 Field Campaign. This dataset consists of the photos taken at Rickyard field (winter wheat) between the 15th and 17th June 2006. For further information on the photos taken on each day please see the associated metadata PDF in linked documentation.

A Delta-T BF2 Sunshine Sensor was used to measure the total and diffuse sky irradiance every minute from 10:30 to 13:00 hours on the 17th June 2006, as part of the Network for Calibration and Validation of EO data 2006 Field Campaign. 150 readings were produced in total. The direct energy of the sun on the instrument is calculated from the differences between the total energy and diffuse component recorded simultaneously.

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. For further details see the dataset's metadata document in linked documentation.

This dataset includes reflectance spectra of Winter oats collected from Fairpiece field, near Chilbolton, as part of the Network for Calibration and Validation of EO data (NCAVEO) 2006 Field Campaign. The data was collected on the 18th June, using an ASD N4406 instrument. For information on the data's processing please see the metadata PDF in linked documentation. Please note that all raw spectra files collected during the NCAVEO campaign (labelled ***R_ASD0606**.***) have incorrect dates, indicating them to have been collected in July rather than June. The day of month and time (UTC) are correct in all cases. All other files (FSF spreadsheets and Excel/ENVI summary outputs) are also marked with the correct 15-18th June 2006 dates.

This dataset compromises data collected by the Compact High Resolution Imaging Spectrometer (CHRIS) over Chilbolton, 17th June 2006, as part of the Network for Calibration and Validation of EO data (NCAVEO) 2006 Field Campaign. The data were collected in Mode 1, which has 34 metre pixel size and 62 spectral bands between 411 nm and 997 nm, giving a ground resolution of 34 metres. Surrey Satellite Technology Ltd is the owner of all data directly resulting from in-flight operation of the CHRIS instrument flown on- board the ESA PROBA spacecraft. All publications on the CHRIS instrument or data obtained from the CHRIS development and/or operation should therefore make explicit reference to Surrey Satellite Technology Ltd, the CHRIS instrument and the ESA PROBA mission. The L3b Directory contains data created by Ted Milton from the L1b, after having been destriped and registered to the OS grid. For more information on the structure and format of the data please see the associated metadata PDF for the dataset in linked documentation.

This dataset contains level 2 vector formatted data derived from the Centre of Ecology and Hydrology's (CEH) Land Cover Map 2000 (LCM2000) data for the Harwood Forest, UK, NCAVEO calibration/validation (cal/val) test site. The NERC funded Network for Calibration and Validation of EO (NCAVEO) campaign was designed to illustrate and explain the processes involved in cal/val of earth observation data.

A Hemispherical Camera (Nikon Coolpix 995) was used to take photographs at sites Harewood Forest, Rickyard and Fairpiece, Chilbolton, as part of the Network for Calibration and Validation in Earth Observation 2006 Field Campaign. This dataset consists of the 19 upward-looking photos taken at Fairpiece field on the 15th June 2006.
