We are pleased to announce a significant upgrade to the remote datasets easily accessible from GMT via the “@” remote file prefix! Here are some highlights - - Updated `@earth_relief`, which now reflects the latest 2.3 SRTM+ release 🎉 - Improved bathymetry predictions for young abyssal hills and small seamounts with `@earth_synbath` ⛰ - New GEBCO [earth relief grids](https://www.generic-mapping-tools.org/remote-datasets/earth-gebco.html) 🗺 - New geopotential grids including the [EGM2008 geoid](https://www.generic-mapping-tools.org/remote-datasets/earth-geoid.html) and Sandwell/Smith versions of [free-air anomalies](https://www.generic-mapping-tools.org/remote-datasets/earth-faa.html) and [vertical gravity gradients](https://www.generic-mapping-tools.org/remote-datasets/earth-vgg.html) 🛰 - New magnetic anomaly grids including the sea surface and 4-km-altitude [EMAG2 anomalies](https://www.generic-mapping-tools.org/remote-datasets/earth-mag.html) from USGS and the [magnetic anomalies represented by WDMAM](https://www.generic-mapping-tools.org/remote-datasets/earth-wdmam.html) 🌎 We now offer 14 remote grids including the previously released datasets for crustal ages, land/sea masks, and day/night imagery!
