Please be aware when you select a "Location" on the form, the latitude and longitude values are rounded to the closest neighborhood point of the degrees grid. Is this true for this dataset? Could you explain what happen with the area selection → (Marc) These details depend on the client application that reads Zarr data and how it deals with subsetting, whether it does any kind of interpolation or not. My assumption is that for an area selection would happen exactly the same as for a single location selection, the closest neighborhood corners of the area polygon would be selected. Please confirm with Eduardo Damasio, and in case of doubt we can check together the code that consumes the Zarr file to confirm this Similarly, selecting an “Area” returns all points within the region defined by the nearest neighborhood corner points to the user-specified S, W, N, and E latitude/longitude values.
