Hi everyone!

I’m trying to calculate the zenith angle. If anyone is familiar with SeaHawk data, I can just extract the longitude and latitude via

`lats = nc1.latitude.data`  
`lons = nc1.longitude.data`

and feed them directly into

```auto
loc = astropy.coordinates.EarthLocation(lon = lons, lat = lats)

```

to get valid results. However, working with OC-CCI data, doing the same returns:

`Coordinates could not be parsed as either geocentric or geodetic, with respective exceptions "from_geocentric() missing 1 required positional argument: 'z'" and "Input parameters lon, lat, and height cannot be broadcast"`

This baffles me completely as there is no difference between the lat/lon numpy arrays originating from SeaHawk and OC-CCI…

Is there a way to work around this or can I calculate the ellipsoid height given the latitude and longitude?

Thanks!

`height` always defaults to 0, for scalar or array inputs in coordinates. Are you sure your `lon` and `lat` have compatible shapes in the second case?
