  • The Earth Radiation Budget Experiment (ERBE) instrument aboard the NASA Earth Radiation Budget Satellite (ERBS) was launched from the Space Shuttle Challenger in October 1984 (STS-41G). The ERBE instrument's main aim was to provide accurate measurements of incoming solar energy and shortwave and longwave radiation reflected or emitted from the Earth back into space. This dataset collection contains colour images (shortwave/longwave/net radiation, albedo, clear-sky albedo, clear-sky shortwave/longwave/net radiation, and shortwave/longwave/net cloud forcing) from scanning radiometers on the three ERBE satellites and for combined satellite cases. Monthly average values are included for the time periods during which the scanners were operational.

  • This dataset consists of combined data from the Earth Radiation Budget Experiment (ERBE) instruments on the Earth Radiaition Budget Satellite (ERBS) and the 9th NOAA Sun-synchronous operational satellites (NOAA-9). ERBS was launched in October 1984 by the Space Shuttle Challenger (STS-41G) into an orbit at 603-km altitude, 57-deg. inclination. NOAA-9 operated at an altitude of 852-km, with an equatorial crossing local time of 1430, having been launched in December 1984.

  • This dataset consists of stock (area) data for landscape features across Great Britain in 1990. Data are presented as areas of Broad (or Priority) Habitats, with associated landscape attributes (such as plant species and land use), within a set of 506 1km squares across Great Britain. The Countryside Survey is a unique study or 'audit' of the natural resources of the UK's countryside. The sample sites are chosen from a stratified random sample, based on a 15 by 15 km grid of GB. Surveys have been carried out in 1978, 1984, 1990, 1998 and 2007 by the Centre for Ecology & Hydrology, with repeated visits to the majority of squares. The countryside is sampled and surveyed using rigorous scientific methods, allowing us to compare new results with those from previous surveys. In this way we can detect the gradual and subtle changes that occur in the UK's countryside over time. In addition to habitat areas, vegetation species data, soil data, linear habitat data, and freshwater habitat data are also gathered by Countryside Survey.

  • This dataset consists of invertebrate species records, sampled from headwater streams during a survey in 1990. Macro-invertebrates were sampled using standard protocols. The sample area in each stream was a single area of stream-bed whose major habitat types can be sampled within the recommended sampling period of three minutes of active sampling, supplemented by a one minute hand search. The length of river surveyed would normally vary from 5 to 15m. Samples were collected using a standard 1mm mesh pond net and returned to the Centre for Ecology & Hydrology (formerly Institute of Freshwater Ecology) for later sorting and identification. Supplemental physical measurements (width, depth, substrate composition) required to run RIVPACS (River Invertebrate Prediction and Classification System) were taken. Data were collected under the Countryside Survey long term monitoring project managed by the Centre for Ecology & Hydrology.

  • This dataset consists of landscape point feature information for points across Great Britain, surveyed in 1990. Data are presented as rows of information recorded as point features (for example individual trees, water bodies or structures), with associated plant species where relevant, within a set of 506 1km squares across Great Britain, surveyed during the Countryside Survey long term monitoring project (note: not all surveyed squares contained point features).

  • The Airborne Arctic Stratospheric Expedition (AASE) which was based in Stavanger, Norway during January and February, 1989, was designed to study the production and loss mechanisms of ozone in the north polar stratospheric environment, and the effect on ozone distribution of the Arctic polar vortex and of the cold temperatures associated with the formation of Polar Stratospheric Clouds (PSC). This dataset contains measurements from the meteorological meteorological measurement system on the NASA ER-2 Aircraft.

  • This dataset consists of stock (length) data for landscape linear features across Great Britain in 1990. Data are presented as lengths of different feature categories (such as fences, walls and lines of trees), with associated species attributes, from 506 km squares, surveyed for the Countryside Survey long term monitoring project (note: not all surveyed squares contained linear features).
