Calypso SVP DRIFTER Data 2022

DESCRIPTION: This data set encompasses observations from all Surface Velocity Program (SVP) drifters deployed from February 18, 2002, to February 2, 2023, during the CALYPSO22 cruise in the Balearic Sea between 31.9°N and 44.4°N, and 1.5°W and 25.1°E. The data 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 February 2, 2023, at which date only five 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.
