File naming convention: *.csv -> comma separated ascii files *_ALMA.nc -> ALMA convention like netcdf files *_CDF.nc -> CDF compliant netcdf file
The period 1992-2011 is the meteorological data for the spin-ip The period 2012-2023 is the meteorological data for the actual simulation
- 4 version exist for the simulation period AMBAVG: annual CO2 increase as in the RCP3PD scenario meteorological data from 1998 (corrected for leap-years where necessary) AMBVAR: annual CO2 increase as in the RCP3PD scenario meteorological data from 1998-2010 ELEAVG: annual CO2 increase as in the RCP3PD scenario + 150ppm from Sept 2012 meteorological data from 1998 (corrected for leap-years where necessary) ELEVAR: annual CO2 increase as in the RCP3PD scenario + 150ppm from Sept 2012 meteorological data from 1998-2010
The files *CO2NDEP_1860-2023.dat contain annual/daily CO2 and N deposition values for spin-up and model simulation
The data were generate using
- hourly data from Princton forcing data set, disaggregated in time using the weather generator of the CABLE model. Comparison of daily data with local site meteorology suggests an acceptable fit.
- annual CO2 are rom the RCP historic period and future RCP3PD scenario (2005-2023)
- eCO2 treatment follows the experimental protocol of the site (pers.comm.)
- N dep follows the relative increase in atm. CO2 and reaches 3 kg N / ha / yr in the year 2000.
Modifications to original data:
- Air pressure has been set to 1013 hPa
- PAR has been generated from incident downward shortwave radiation, assuming a conversion factor of 2.3 umol/m^2/s per W/m^2
- VPD and RH have been calculated from Qair using the approach of Montheith & Unsworth 2008
- Wind data have been taken from Bernard Pak, derived with Cable from the Sheffield climate data 1992-2008. Values for 2009-2011 correspond to those of 1992-1994
- solar noon was corrected to be at 12 hours!
