read_ef_file
(Package: efreadr) :
Load a CSV file from the European Flux Database
File name is parsed to extract year, site identification and aggregation type. The file name must point to a valid European Fluxes file, in CSV format and must resolve to a valid file format name.
The European Eddy Fluxes Database Cluster distributes fluxes of different Green House Gases measured mainly using the eddy covariance technique acquired in sites involved in EU projects but also single sites in Europe, Africa and others continents that decided to share their measurements in the database (cit. http://gaia.agraria.unitus.it ). The package provides two functions to load and row-wise bind CSV files distributed by the database. Currently only L3 and L4 (L=Level), half-hourly and daily (aggregation) files are supported.
