Description

The parameter used for forecasting magnetic activity in the 27 day forecast is a daily index. It is known as DRX and is the average of the hourly ranges (maximum minus minimum during each hour) in the X (northward) component of the magnetic field intensity for a day (the UT or GMT day). For example, the DRX for the zone is the mean of 24 values. The units are nanoteslas (nT).
