We found some differences between WRF3.9.1 MODIS 15s and 30s land cover in China. Can someone explain these? Thanks for your help in advance! We plot these figures of MODIS 15s and 30s land cover as follows:

We do realize some difference between MODIS 30s and MODIS 15s. Before we come up with a solution, would you please stay with the MODIS 15s data? This is because our preliminary examination shows that the 15s data is more realistic.

Thanks for your reply.
Our domain resolution is 27km and clearly urban categories using the 15s MODIS data do not represent urban areas in China realistically. The 30s data look a little bit better considering urban areas. Please advice!
 
I don't think 27-km is a good option for describing urban lands type. I am actually perplexed why the 30s modis data yields better results than 15s data. Our test shows that the 15s data can better show the geographic distribution of lands type.
