In the best practices guide for WPS (link), it states that "It's best to keep the ratio of input data resolution to the coarsest grid resolution (on your domain) to no more than 1:10". So, my questions are:
- This imposes a lower limit for the grid spacing of the coarsest domain, in other words, . Is that correct? Sorry if the question sounds silly, but 1:10 being less than 1 makes the 'more than' wording confusing to me. Because if the implication is literally, this means that for 80 km input resolution, coarsest grid resolution should be minimum 800 km, which is not what I see in the research papers (also the example in the link contradicts, where this ratio is 2.96).
- If so, is there a recommended upper limit for the grid spacing of the coarsest domain?
