PACKAGE DESCRIPTION: This gridded product consists of a global (80°S-62°N) climatological estimate of radiocarbon content (∆14C) at half-degree horizontal resolution, provided both on neutral density and depth surfaces. It is based on the GLODAPv2 data compilation (Key et al. 2016, Olsen et al. 2016) and the neutral density (γn; Jackett and McDougall 1997) field of the WOCE global hydrographic climatology (Gouretski and Koltermann 2004). The mapping has been performed separately along 140 neutral density surfaces, using the distance look-up system described in the data product documentation, following the procedure described in de Lavergne et al. (2017).
