attribute	NC_GLOBAL	summary	String	The data of all the Surface-Velocity-Program (SVP; https://gdp.ucsd.edu/ldl/svp/) drifters deployed during the CALYPSO22 cruise in the Balearic Sea were processed to give positions (latitude and longitude), zonal and meridional velocities, and sea surface temperature (SST) records at uniform and common times. The processing was done on the data between the deployment times and 2 Feb. 2023, at which date only 5 SVP drifters were still alive. The CALYPSO22 raw drifter data were edited to exclude data before deployment and to remove obvious outliers using the method described in Menna et al. (2017). If a drifter was recovered and redeployed, the data were separated into two files. Even though the nominal sampling period was as small as 5 min., gaps without data for longer periods occurred in the time series. In case of temporary stranding or pick-up and for gaps larger than ~1 day the time series were split into separate files. For some drifters with transmission problems and numerous data gaps, the records were simply cut at the first occurrence of a gap. The edited data were linearly interpolated at 5-min. intervals. Velocities were estimated by central finite differences of the interpolated positions. Finally, the data were low- pass filtered with a Hamming window of 30 and 60 minutes.
