Surface Drifter trajectory data and marine environmental field data sets

1. Surface drifter track data set using the 2010-2023 sea surface drifter data set of 10°-25° North latitude and 105°-125° East longitude. The data set is derived from the Global Drifter Program (GDP). The sea surface temperature, salinity, and ocean current data set of 10°-25° North latitude and 105°-125° East longitude from 2010 to 2023 were used in the Marine environmental field dataset, with a time resolution of 3 hours and a spatial resolution of 0.08°×0.04°. The dataset is derived from Hycom Global Forecast data.2. The GDP data set uses 69473 data pieces, with row labels as the number of data pieces and column labels as id, time, lat, lon, sst, ve, vn, spd, var.lat, var.lon, var.temp. The meanings represented respectively are drifter ID, time, latitude (°), longitude (°), sea surface temperature (° C), drifter eastbound velocity (cm/s), drifter northbound velocity (cm/s), drifter combined velocity (cm/s), latitude variance, longitude variance, and temperature variance.3. There is data missing in the GDP data set, which is due to a problem in the transmission of drifter data. For the completeness of the experiment, the missing data sets were removed.4.Hycom data set selects the Marine environmental field data within ±0.5° range according to the drifter latitude and longitude data for calculation. 1.
