CLM5.0 self define high resolution output has low resolution grid

Hi there, I followed the instruction to generate surfdata for a 1km resolution for CLM 5.0, and used the compset: I2000BgcCropGs. However, I found that the output is truly 1km resolution but with big grid, just like a mask on the top, here is the output figure:

It can be seen the output with terrain effect, but with low resolution grid on the top. So, I think this might be caused by the other input datasets, such as forcing data and so on. Here is a list of all input data used in this compset:

... The omitted part includes similar meteorological forcing data.

As I found that the low resolution grid is about 2.5 degree, so I checked all the inputlist and there is only one input data is 2.5 degree, I wonder if we can eliminate this grid effect by replacing this 2.5 degree data.

I look forward to and would appreciate any reply!

By the way, the 2-degree data that you highlighted is "finidat" so initial conditions. The effect of initial conditions should dissipate over time.

However, in the above list I also see 1-degree data and half-degree data and T62 data. You may have to replace all of that with 1-km data for what you're trying to accomplish.

Hi, slevis. Thanks for your reminding, I will have a try.
