+ | ==== Create the met-data ==== | ||
+ | First run the model to produce 6 hourly data. The following namelists are needed: | ||
+ | |||
+ | < | ||
+ | user_nl_cam | ||
+ | &camexp | ||
+ | mfilt = 1, 4, | ||
+ | nhtfrq | ||
+ | avgflag_pertape =' | ||
+ | fincl2 | ||
+ | </ | ||
+ | |||

+ | user_nl_clm | ||
+ | &clmexp | ||
+ | hist_mfilt | ||
+ | hist_nhtfrq | ||
+ | hist_avgflag_pertape | ||
+ | hist_fincl2 | ||
+ | </ | ||
+ | |||
+ | ==== Use the met-data in another run ==== | ||
+ | |||
+ | First create a compset which has the configure-option " | ||
+ | |||
+ | Then use this compset to create a case. You need the following user-input (for example in your user_nl_cam) | ||
+ | |||
+ | < | ||
+ | & | ||
+ | met_data_file='/ | ||
+ | met_filenames_list = '/ | ||
+ | </ | ||
+ | |||
+ | This info can be added directly in a use_case which you associate with the compset created (see e.g. 2000_cam5_oslonudge.xml) | ||
+ | |||
+ | where met_data_file is the first met-data file to read, and met_filenames_list is a list of the following met-data. The first lines of the file should look something like this (guess what the rest of the file should look like? 8-o: ) | ||
+ | < | ||
+ | / | ||
+ | / | ||
+ | / | ||
+ | </ | ||
+ | |||
+ | This file can be created at the place where you put the metdata with this command: | ||
+ | < | ||
