.. _examples-aurora_forecast: Plotting the Aurora Forecast from NOAA on Orthographic Polar Projection ----------------------------------------------------------------------- The National Oceanic and Atmospheric Administration (NOAA) monitors the solar wind conditions using the ACE spacecraft orbiting close to the L1 Lagrangian point of the Sun-Earth system. This data is fed into the OVATION-Prime model to forecast the probability of visible aurora at various locations on Earth. Every five minutes a new forecast is published for the coming 30 minutes. The data is provided as a 1024 by 512 grid of probabilities in percent of visible aurora. The data spaced equally in degrees from -180 to 180 and -90 to 90. .. plot:: examples/aurora_forecast.py .. literalinclude:: aurora_forecast.py
