where these files are available. These subsets may also be searched for in ESDI.

NOTE: Mismatch between data and legend.
Please note the following errors while trying to match the data and the legend for the 1km and 8km products.
In the 1 km AVHRR land cover classification product, Code value 14 is used to represent Urban and Built class instead of Code value 13 as in the legend above.
In the 8km AVHRR land cover classification product, code 13 represents regions with "permanent snow and ice" and not "urban and built". While code 14 shouldn't exist, it appears erroneously in the dataset over areas with bare ground and water. If code 14 appears over Greenland, Antractica or similar icy areas, please recode the data to code 12. If some code 14 values appear along the image borders in the ocean, please recode these to code 0 which is water.
