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

C1, C2, …, C12 = monthly sunhsine (%)

The last variables are the plant functional types: temperate broadleaved evergreen trees (tbe), temperate summergreen trees (tst), temperate evergreen conifer trees (ctc), boreal evergreen trees (bec), boreal deciduous trees (bs), temperate grass (tg), C4 grass (trg4), woody desert plant type (wd), tundra shrub type (tus), cold herbaceous type (ch), anthropogenic type (hum).
