Global Canopy Conductance (Gc)

This product provides estimates of canopy conductance at a global scale (0.05⁰) based on MODIS reflectance from MCD43C4 product and three vegetation indices (NDVI, EVI and Kc). The data is produced globally at 0.05⁰ and every 8 days. Monthly and anuual climatologies are also available.\n\nBase Period for Climatology: 2001-2011 \n\nExtra information about the pixel values:\nUnits: mms-1\nMultiply by scale factor: 0.001\nFill values: -9999\n\nThe full reference for the algorithm is: \nYebra, M., Van Dijk, A., Leuning, R., Huete, A., Guerschman, J.P., 2013.
