example #1:   aetxLPJxC1SuCVA4020i.nc.gz

variable = aetx (total actual evaporation)
model = LPJx (Lund/Pik/Jena)
GCM model = C1  (CGCM1)
GCM experiment = Su (sulphate aerosols)
CO2 experiment = C (increasing CO2)
vegetation = V (VEMAP vveg2)
time step = A (annual)
release = 4020
grid representation = i (inflated)
compression = .gz (gzipped)
example #2:  laiwMC1xH2SuxVA3010i.nc
variable = laix (woody LAI)
model = MC1x (Oregon State Univ; USDA Forest Service-MAPSS Team)
GCM model = H2  (Hadley HADCM2)
GCM experiment = Su (sulphate aerosols)
CO2 experiment = x (constant CO2)
vegetation = V (VEMAP vveg2)
time step = A (annual)
release = 3010
grid representation = i (inflated)
compression = - (uncompressed)
