Historical Upper Air Meteorological Data for Global Stations 1990-1993

Australia GTS Upper Air is a historical meteorological dataset containing upper air observations from scattered global stations. The dataset, archived at the National Climatic Data Center, comprises data for the years 1990 through 1993. It was originally received in Australia via the Global Telecommunications System and is part of the larger Comprehensive Aerological Data Set (CARDS).

Use Cases

• Analyzing temporal trends in upper-air pressure and temperature across global stations from 1990-1993.
• Studying vertical profiles of relative humidity and wind patterns for specific stations and time periods.
• Comparing raw GTS data against the quality-controlled CARDS (DSI-6305) dataset to assess data processing impacts.
• Correlating wind speed and direction observations with historical weather event records.

Strengths

• Data spans a 4-year period from 1990 to 1993.
• Includes major upper-air parameters: pressure, temperature, relative humidity, wind speed, and direction.

Limitations

• Dataset is described as a 'small historical data set' with unknown row count.
• Data was not quality controlled by the NCDC, unlike the larger CARDS dataset.
• Temporal coverage ended in 1993, making the data over 30 years old.
