[{"name":"geoffroy-2022-argoit-1","title":"Global map of the total semidiurnal internal tide variance at 1,000 dbar from Argo data","summary":"This dataset is a global map, on a regular 2.5\u00b0 \u00d7 2.5\u00b0 grid, of the total semidiurnal internal tide variance at 1,000 dbar. It is computed from in situ temperature and pressure time series recorded during the park phase of Argo floats.\r\n\r\nThe total semidiurnal internal tide variance is not affected by phase decorrelation but only by mixing, scattering, and nonlinear processes. The geographical distribution of the total variance can therefore be used to better understand these decay processes. \r\n\r\nThe original Argo data used to produce this dataset are scattered at the global scale and span the period 2004\u200a\u2013\u200a\u20602022. The final gridded product is obtained by complex demodulation of local mean autocovariance series of the isotherms vertical displacement at 1,000 dbar.","citations":"Argo (2000) Argo float data and metadata from Global Data Assembly Centre (Argo GDAC).
