definition: LTMS objectives: * Provide weather data from surface and upper air measurements for forecasting and showing climatic trends * Observe annual changes in upper atmosphere ozone concentrations * Sample air and snow to monitor changes in greenhouse gases in the atmosphere and in the ice * Measure global lightning and wave activity in the magnetosphere * Measure the temperature of the mesosphere (87 km above the Earth’s surface) * Monitor selected marine species in the Scotia Sea * Measure changes in ocean currents, nutrients and temperature * Take sea-ice observations to identify annual and ten-year trends * Survey the diversity of groups of organisms on land and at sea * Carry out geological and geophysical surveys, and surveys of ice and surface features in British Antarctic Territory
