Global Magnetic Drifter Pilot Project Data Format<\/h1>\n

Data format<\/h3>\n

The APS magnetic sensor made a measurement for 128 seconds every 20 minutes. Those 128 samples were averaged into one value of X,Y and Z magnetic field value. Every 4 hours the data were sent via Iridium to the Argo drifter database website<\/p>\n

Once a day (every 24 hrs) a calibration cycle was run where 256 sequential raw data values were recorded. The data fields are ascii with an identifying first character to describe the type of data.<\/p>\n
