Land-Based Station Data

Measuring Instruments used for current observations and data reporting

Measuring instruments used for current observations and data reporting

Land-based observations are collected from instruments sited at locations on every continent. They include temperature, dew point, relative humidity, precipitation, wind speed and direction, visibility, atmospheric pressure, and types of weather occurrences such as hail, fog, and thunder. NCDC provides a broad level of service associated with land-based observations. These include data collection, quality control, archive, and removal of biases associated with factors such as urbanization and changes in instrumentation through time. Data on sub-hourly, hourly, daily, monthly, annual, and multiyear timescales are available.
