Globe-LFMC, a global plant water status database for vegetation ecophysiology and wildfire applications
Posted on 2019-10-24 - 10:32
Globe-LFMC is an extensive global database of live fuel moisture content (LFMC) measured from 1,383 sampling sites in 11 countries: Argentina, Australia, China, France, Italy, Senegal, Spain, South Africa, Tunisia, United Kingdom and the United States of America. The database contains 161,717 individual records based on in situ destructive samples used to measure LFMC, representing the amount of water in plant leaves per unit of dry matter. The primary goal of the database is to calibrate and validate remote sensing algorithms used to predict LFMC. However, this database is also relevant for the calibration and validation of dynamic global vegetation models, eco-physiological models of plant drying as well as understanding the physiological drivers of spatiotemporal variation in LFMC at local, regional and global scales. Globe-LFMC should be useful for studying LFMC trends in response to environmental change and LFMC influence on wildfire occurrence, wildfire behavior, and overall vegetation health.
Change Notice - Globe-LFMC, a global plant water status database for vegetation ecophysiology and wildfire applications:
Globe-LFMC-v2.xlsx - Some site’s coordinates from Spain and California were affected by a wrong transformation between coordinate reference systems.
The original Spanish UTM coordinates were mistakenly considered to be in the geodetic datum WGS84 instead of the ED50 datum. Thus, those original coordinates have been transformed again, using the correct datum.
The original Californian UTM coordinates were mistakenly considered to be in the geodetic datum WGS84 instead of the NAD27 datum. Thus, those original coordinates have been transformed again, using the correct datum.
As a consequence of these changes, the columns “Land Cover”, “NDVI CV min”, “NDVI CV max”, “NDVI SD min”, “NDVI SD max” have been corrected and updated.
