GFS forecast

Before each flight, we use recent GFS forecast output to shown the general atmospheric, oceanic, and sea ice conditions we are going to expect at the time of our SIZRS flight. Forecast results  will be updated on a daily basis within one week of the next flight. Due to the changes of the Coast Guard ADA flight scheduling, the Forecast valid time will also change accordingly. In most cases, we will target 22Z of the flight day.
