Global Drifter Program - Climatology - Annual Means

Annual Means of Drifter Data. NOAA/Atlantic Oceanographic & Meteorological Laboratory (AOML) & Univ. Miami data from a local source.

cdm_data_type = Grid
VARIABLES (all of which use the dimensions [longitude][latitude]):
U (Zonal velocity, meters per second)
V (Meridional velocity, meters per second)
SST (Sea surface temperature, degree_C)
eU (Standard error of zonal velocity, meters per second)
eV (Standard error of meridional velocity, meters per second)
eSST (Standard error of sea surface temperature, degree_C)
N (Number of drifter-days per square degree, drifter-days per square degree)


Global Drifter Program - Climatology - Current Variance

Current variance (eddy kinetic energy) derived from residuals with respect to the time-mean, seasonal, spatial gradient, and SOI-related currents

cdm_data_type = Grid
VARIABLES (all of which use the dimensions [longitude][latitude]):
Up2bar (Zonal Velocity Variance, mean(u-prime-squared), (meters per second)^2)
Vp2bar (Meridional Velocity Variance, mean(v-prime-squared), (meters per second)^2)
rA (Variance Ellipse semimajor axis, (meters per second)^2)
rB (Variance Ellipse semiminor axis, (meters per second)^2)
angle (Orientation Angle of Variance Ellipse, degrees: 0=east/west, 45=northeast/southwest, 90=north/south)
N (Number of drifter-days per square degree, drifter-days per square degree)


Global Drifter Program - Climatology - Monthly Means

Monthly Means of Drifter Data. Please note, this dataset does not include the variable N, or number of drifter-days per square degree. To retrieve the variable N, use the variable N in the Climatology - Annual Means dataset. NOAA/Atlantic Oceanographic & Meteorological Laboratory (AOML) & Univ. Miami data from a local source.
