About this Collection

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. Base Period for Climatology: 2001-2011 Extra ... more

Algorithm description


Below the calibrated equations to generate the canopy conductance product Gc_NDVI=2^(4.11 (NDVI-〖NDVI_min)) Gc_EVI=〖2.5〗^(3.15(EVI-〖EVI〗_min)) Gc_Kc=〖0.3〗^(5.14k_c ) Gc_final=average(Gc_NDVI,Gc_EVI,Gc_Kc)


To produce this product we make use of MODIs data downloaded from ftp://e4ftl01.cr.usgs.gov/MOTA/ MCD43C4.005/

About this Project

1212.0 OCE Post Doc Marta Yebra


Enhanced carbon capture through vegetation growth can affect water resources by increasing vegetation water use. This Postdoctoral research aims to improve our understanding of the tradeoffs between carbon capture and water resource availability using a combination of satellite observations, field measurements, and biophysical modelling. The unders... more

Final mapping


The algorithm described in Yebra et al 2012, RSE was applied globally to map canopy conductance, every 8 days as well as derived monthly and annual climatology


Observation


Vegetation indices derived from MODIS data (MCD43C4, downloaded from ftp://e4ftl01.cr.usgs.gov/MOTA/ MCD43C4.005/ in February 2012)
