Hello, Our team is working on gridded products (EASE-Grid 2.0) that indicate surface snow extent, derived from several different sources. CF compliance is one of our project goals. Initially I thought that surface_snow_binary_mask would be an appropriate standard name for our terrestrial snow variables. However, the definition explicitly states the values of 1 and 0 are used with this standard name.
Here's an excerpt of data flags in each pixel of our terrestrial snow product, which are more complex. Layer 1: Fused snow extent 1000 - MODIS, Passive Microwave (PM), and IMS report snow 1001 - MODIS and PM report snow 1002 - MODIS and IMS report snow 1003 - PM and IMS report snow 1004 - MODIS only reports snow 1005 - PM only reports snow 1006 - IMS only reports snow 2000 - Snow free land 4000 - Ocean Layer 2: IMS snow extent 1000 - Snow covered land 1001 - Ocean converted to snow covered land (result of a consistent land/ocean binary mask applied to all source products) 2000 - Snow free land 2001 - Ocean converted to snow free land 4000 - Ocean 4001 - Snow covered land converted to ocean 4002 - Snow free land converted to ocean What options do we have to achieve CF compliance? Any help would be greatly appreciated. Kind regards, Tom --- Thomas Estilow Rutgers University Global Snow Lab [email protected]
