The graphs show Artificial Neural Network (ANN) predictions of the atmospheric seeing conditions at the Compact Array. The predictions are based on numerical models of the atmosphere. The ANN has been trained to forecast the output of the 21GHz (formerly 30GHz) seeing monitor located on site, using 10 years of historical data.
The Global Forecast System forecast updates four times per day. The latest, and previous, predictions are shown above.(Updated 30-Jan-2015 David Brodrick)
