- Requests can include up to 32 heights; very low levels may be refused when the model's lowest usable level sits higher.
Field notes
A request supplies latitude, longitude, time, up to 32 altitudes, and an altitude reference; the example uses above-ground heights near Mojave. The recorded response includes paired AGL and MSL altitude values and identifies the model run, time step, and grid point. Coverage is forecast-only, and the page says heights near the surface may be rejected when below the model's lowest usable level; ERA5 history is described as planned.
