EUROFlux Meteorology, Energy, Soil and Carbon Flux Data (15 flux towers) 05/10/2009 ************************************************************************************************* DESCRIPTIONS: This data set is daily aggregated flux tower measurments for meteorology, energy, soil and carbon fluxes from the semi-hourly data provided by the EUROFlux. This data set was processed by Ke Zhang at NTSG, The University of Montana,based on the original semi-hourly EUROFlux Level4 data. According to the EUROFlux Fair-Use Data Agreement, the EUROFlux data are freely available. However, the users have to inform the appropriate EUROFlux scientist(s) of how you intend to use the data and of any publication plans. It is the users' responsibilties to obey the data agreement. ************************************************************************************************** SITE LOCATIONS & DATA AVAILABILITY: There are 15 sites in this data set.
