Climatic variations of several variables - Holocene
The dataset gives the variations of several climatic variables on the 0–10,000 year BP period by increment of 100 year.
The variables are reconstructed using pollen data and an inverse vegetation model (BIOME4). The variables are expressed in term of anomalies according to their present reconstructions (0–100 years BP).
The resolution of 100 years is certainly not reached for all the pollen diagrams used in the reconstruction. It is rather a maximum resolution. In reality, the time-series at that time step are rather smoothed and it should be unrealistic to interpret events with a length inferior to several centuries.

- Statement
-
The R file contains two tables, reco2 [time, gridpoints, variables] of the anomalies reconstructed from 9900 year BP to 0 year BP by steps of 100 years, for 81 regional gridpoints, for 68 variables.
Significance of the variables :
CO2: CO2 concentration in the atmosphere
S2 - not useful
LONG longitude
LATI latitude
ALTI altitude
SOILK1, SOILK2, SOILW1, SOILW2 soilcharacteristics used according to FAO
Tmin minimal daily temperature, °C
Biome = biome type according to BIOME4 typology
NPPtot = total net primary production kg m−2 years−1
MTCO = mean temperature of the coldest month
MTWA = mean temperature of the warmest month
E/PE = ratio actual evapotranspiration over potential evapotranspiration
P-E = annual total precipitation minus actual evapotranspiration, mm
GDD5 = growing degree days above 5°C
TANN = annual mean temperature, °C
PANN = annual total precipitation, mm
T1, T2 … T12 = monthly mean temperature (Jan to Dec), °C
P1, P2, … P12 = monthly total precipitation (Jan to Dec), mm
