The origin of the graticule (0,0) is defined by where the Equator and prime meridian intersect. The globe is then divided into four geographical quadrants. North and south are above and below the Equator, and west and east are to the left and right of the prime meridian. Latitude and longitude values are traditionally measured either in decimal degrees or in degrees, minutes, and seconds. Remember, they are angular measurements.

As explained by ERA5 (2020), the ERA5 data is produced and archived on a reduced Gaussian grid which is a series of evenly spaced data points on each ‘spherical circle’ (latitude), and parallels (longitude) spaced at quasi-regular intervals, cf. Figure 1. All gridded data is made available in decimal degrees, with latitude values in the range referenced to the equator and longitude values in the range [0; 360) referenced to the Greenwich Prime Meridian.

Users can switch between base layers through the selector that is located on top of the map area: OpenStreetMap and other base layers or a simple white background with administrative borders. On the left of the base layer selector there is a control which shows the geographic coordinates when the mouse cursor is moved over the map. In order to provide a better understanding of the coordinates, these coordinates are provided in decimal degrees.
