SET Forecast Products


SET provides real-time and forecast data services for describing the solar-terrestrial environment. These services are tailored for unique user communities. Below are selected indices from SET and our partners that are related to space weather.

Premier SET operational services offer forecasts from the current epoch to 6-hours at a 1-minute cadence, to 72-hours at a 3-hour cadence, and to 137 days at a daily cadence. Original and value-added data have latencies ranging from 5 minutes to 24 hours and cadences ranging from 1 minute to 24 hours.

Advantages of SET Forecasts

SET forecasts are automatically updated on operational servers at the highest relevant geophysical cadence and lowest latency possible. Our systems use redundant data streams to provide enhanced, primary data and climatological, backup data to generate our data products. SET uses a secure environment to ensure that quality products are delivered on-time to our customers.

E10.7 and F10.7 Forecasts

Space Environment Technologies has actively developed forecast products since 2001, starting with the F10.7 and E10.7 solar indices. The example of these forecasts that are issued every hour is shown in the figures above. We have compared the F10.7 and E10.7 forecasts to the official NOAA Space Weather Prediction Center's forecasts and validated them for a 200-day forecast run, every 3 hours, from January-July 2001 during high solar activity. The figure below graphically demonstrates the comparison for this period of time near the solar cycle maximum when predictions are the most difficult. The figure shows comparisons between the 1, 2, an 3-day values of the NOAA/SWPC (SEC) F10.7 forecasts (red) to SET F10.7 forecasts (blue); it can be seen the SET forecasts either meet, or improve, the SEC F10.7 forecasts. Furthermore, the E10.7 forecasts (in units of F10.7) show a more significant improvement

E10 vs F10 comparison

A sample of one of the forecast products, shown below, provides the issued E10.7 and F10.7 values for the past 160 days, and their predicted values out to 6-monhts in the future. Error bars indicate 1-3 standard deviations (green 1, yellow 2, red 3). Recall that E10.7, in units of F10.7, is a proxy EUV index that can be used to improve models and algorithms simply by replacing F10.7 values: no other changes are required
