mapped_pv_all_sources_2010

The potential vorticity calculated from the vertical gradient of the neutral density (ie. PV = f/rho_0 d(gamma)/dz) for the year 2010 (with annual and semi-annual harmonics) from 75S to 30S.本数据集为2010年由中性密度（neutral density）的垂直梯度计算得到的位势涡度（potential vorticity，即 PV = f/ρ₀·d(γ)/dz），包含年谐波与半年度谐波成分，覆盖纬度范围为南纬75°至南纬30°。
