Historical AVHRR Polar Winds Data

A 28-year tropospheric wind data set covering both polar regions has been generated. The product covers the area poleward of approximately 65 degrees latitude, using the historical Advanced Very High Resolution (AVHRR) Global Area Coverage (GAC) data from NOAA satellites. This product extends the real-time MODIS and AVHRR the records back 20 years, providing an invaluable product for the verification of, and assimilation in, climate prediction models. The period of coverage is currently 1982-2009. Additional years will be added as the data become available.
