There are two types of files for this project. The one-day averaged currents 
are located in the C*.cdf files. These files contain time, latitude, longitude
and 15m current components from drifters. They can be read with read_C.c.

The PosWind*.cdf files contain time, latitude, longitude, 15m current 
components and wind speed and direction. These files can be read with
read_PosWind.c.

Both C programs can be found on the Tools page.
