The Airborne Research & Survey Facility (ARSF, formerly Airborne Remote Sensing Facility) is managed by NERC Scientific Services and Programme Management. It provides the UK environmental science community, and other potential users, with the means to obtain remotely-sensed data in support of research, survey and monitoring programmes. The ARSF is a unique service providing environmental researchers, engineers and surveyors with synoptic analogue and digital imagery of high spatial and spectral resolution.The NEODC holds the entire archive of Airborne Thematic Mapper (ATM) and Compact Airborne Spectrographic Imager (CASI) data acquired by the NERC ARSF. High-resolution scanned digital versions of the entire collection of analogue photographs are now also available as well as selected LiDAR-derived elevation and terrain models for selected sites flown using the sensor.

Urban water quality and hydrometric data for a range of urban developments in in the south of England. Water quality has been obtained from fortnightly-monthly sampling of river water using a Manta 2 sonde, and includes the parameters: ammonium, DO, pH, specific conductivity, temperature and turbidity. Rainfall was measured using a number of 2mm tipping bucket raingauges across the urban sites and through QC deriving a 15min time series of rainfall in millimetres for each site. Flow in cumecs was derived from in-situ stream channel measurements of velocity and depth using ultrasonic flow monitoring gauges.
