    how to use gcc compiler on derecho

    Hi,all, I am porting my model (CLM5 )from a gcc compiler platform to derecho, it works well with gcc compiler. but derecho seems only has default intel compiler, as I did not find any gcc tag in config_compiler.xml and config_machine.xml for derecho. Is there anyone can share how to use gcc...

    Use of the CLM land use tool to create land time series data in standard CLM format

    Hi,everyone! I have recently generated land use data for the years 2015–2100. My data format is similar to LUH2, but the land unit in my data represents the area (in square kilometers) of different land types within each grid cell. My land use data includes seven plant functional types (PFTs)...

    Why the `o3coefg` in the PhotosynthesisMod.F90 only used for rs_z rather than gs?

    Hi everyone, I am doing some studies about ozone-vegetation feedback. And the ozone can damage the vegetation's stomatal conductance. I have seen the source code in the `PhotosynthesisMod.F90` file. The ozone damage factor for stomatal conductance (`o3coefg`) only affects `rs_z` (resistance)...

    The error when running FHIST for the period 1980-2020.

    Hi, I want to run a simulation for 1980-2020 using the compset FHIST, but the model stopped when it reached 2015. I checked the log file, and the error shown is: ERROR: GETEIL: FAILED to get Inputdata/atm/cam/strataero/ ozone_strataero_WACCM_L70_zm5day_18500101-20150103_CMIP6ensAvg_c180924.nc...

    Questions about using lai_streams in CLM5

    I want to use a LAI with interannual variability (1980-2020) in the model. From previous posts, I roughly understand that lai_streams can be used to achieve this, but I still have some doubts that I hope you can help me clarify. The compset I am using is FHIST...

    Running CLM5 and DATM in different resolutions

    Dear colleagues I am running CLM5 in a 3 km resolution regionally over the EU-CORDEX domain. Thus far, our model worked with forcings that we downscaled to this 3km EU-CORDEX grid without problems. Now, I need to run the same clm5 model but with 12 km resolved forcings (over the same domain). I...

    How is surfdata's variable monthly_lai obtained?

    Hi, I am using the surfdata file 'surfdata_1.9x2.5_16pfts_Irrig_CMIP6_simyr2000_c170824.nc' and have taken the weighted average of the 'monthly_lai' variable from the model’s default surfdata to compare it with GIMMS LAI data. In the CLM5 technical manual, I saw that the LAI values in the...

    How to convert SOILLIQ (kg/m^2) to H2OSOI (m^3/m^3) from clm output

    Hi, SOILLIQ and H2OSOI both reprsent the soil moisture. I would like to convert SOILLIQ (kg/m^2) to H2OSOI (m^3/m^3), which have different units. But I have no idea how to do. I am looking forward to any suggestions. Thanks in advance. Best, Kaiwen
