-## Directory structure for the data from different projects
-Input data can be from various models, observations and reanalysis data that adhere to the [CF/CMOR standard](https://cmor.llnl.gov/). ESMValTool uses several categories (in ESMValTool, this is referred to as projects) for input data based on their source.
-The current categories in the configuration file are mentioned below. For example, CMIP is used for a dataset from the climate model intercomparison project whereas OBS for an observational dataset. For each category, you can define either one path or several pathes as a list.
