  5. RS modes

  6. Parameterisations • Soil T: (0-5, 5-15, 15-50, 50-100 cm; 1-2 m) • WR 150 mm, WG 40 mm,WC = 0.1*Aveg*Aleaf*ATile , WN = inf.

  7. ‘Time-invariant’ surface var’s. • "/data3/mjf/FORCING/FORCING_EQY1_MUNICH_IPILPS1.txt” • "/data3/mjf/CHASM/chasm_current/OUT_CHASM/MUNICH/” • EQUIL 0. • HEIGHT 20. • Z0G 0.01 • Z0N 0.00024 • RCMIN 40. • MMFVEG 999. 0.9 0.9 0.9 0.9 0.9 0.9 0.9 0.9 0.9 0.9 0.9 0.9 • MMLAI 999. 5.0 5.0 5.0 5.0 5.0 5.0 5.0 5.0 5.0 5.0 5.0 5.0 • WRMAX 150. • ALBV 0.15 • ALBG 0.2 • ALBN 0.75 • Z0V 0.1 • IYRS 20. • IDAYS 365 • TS 281. • WR 75. • WN 0. • RHON 100. • EOF 0.

  8. ICHASM Isotope module • H2O reservoirs are well-mixed with inputs • Mixing: RN = RN1 + RN2 • Fractionation: R = R0f(a-1)ekin = (1-h)nCD103, 0.5 < n < 1, CD = 28.5 (18O), 25.1(2H)aevap = akin + aeq • Selection:‘run-off’ = excess - max. storage capacity

  9. ICHASM LSDRV: forcing variables CHASM: Prec. mixing LSEB1: skin temperature, evaporation LSMB: water reservoirs LSEB2: soil T. and snow melt

  17. Overview • How ICHASM works, it’s tile structure and 4 water reservoirs (WG, WR, WC, WN) + isotopes, parameterisation of hydrological process (evaporation, run-off) • Results from ICHASM at different timescales, EQY1 • How ISOLSM works, soil, vegetation, hydrology and isotope modules

  19. ISOLSM

  20. Parameterisations • Soil : (0-10, 10-40, 40-100 cm, 1-2, 2-4, 4-6 m) • WR ~6 m, WC = 0.1*(LAI+SAI)*AT
