A method is proposed for obtaining the in‐track wind component by exploiting the different ways in which two satellite‐borne instruments interact with the airstream. It makes possible the completion of the three‐dimensional wind vector from measurements which yield at most two components. This is especially important during geomagnetic storms when winds can cause serious errors in density measurements made by a single instrument. The method can be used to retrieve valuable information from existing data bases which contain measurements by three‐axis accelerometers and chambered instruments such as closed‐source mass spectrometers or pressure gages.
