Observed ecological inputs, 2004-2016, for running the Community Land Model 4.0 for Hawaii

Published by Climate Adaptation Science Centers | Department of the Interior | Metadata Last Checked: July 18, 2025 | Last Modified: 2018-11-20
The following files contain source data for use of the Community Land Model 4.0. Included are: Biometric data: 1) Growth increment data for Thurston and Olaa, based on dbh surveys done in four 10 m by 10 m plots at over a 12 year time period at Thurston and at six plots overs a 12 year period at Olaa, 2) Field measured leaf area index data. Measurements were made using LAI-2000 and LAI-2200 instruments, 3) Litterfall from Thurston and Olaa over a 17-mo period from June 2014 to Sep 2015. Data were sorted by species/litter type. Data are weights., 4) Field measured soil respiration data scaled to annual values and compared with tower-based measurements of ecosystem respiration. Leaf data: Leaf-scale gas exchange rates were used to compare the ecophysiological traits of the native species (Metrosideros polymorpha) and the invading species (Psidium cattleianum). Meteorological data: Meteorological data measured at Olaa and Thurston towers, including the following variables: Variable name Units Description TimeStamp Date and time RNET_SCR W m-2 Net radiation K dn_SCR W m-2 Downward shortwave radiation K up_SCR W m-2 Reflecrted shortwave radiation Ldn_SCR W m-2 Downward longwave radiation Lup_SCR W m-2 Upward (emitted) longwave radiation PAR_SCR µmol m-2 s-1 Photosynthetically active radiation T_HMP_SCR C Air temperature RH__HMP_SCR % Relative humidity H2O_hmp_SCR g cm-3 Specific Humidity Pressure_SCR kPa Air pressure shf_avg1_SCR W m-2 Soil heat flux at 8 cm depth (1) shf_avg2_SCR W m-2 Soil heat flux at 8 cm depth (2) shf_avg3_SCR W m-2 Soil heat flux at 8 cm depth (3) shf_avg4_SCR W m-2 Soil heat flux at 8 cm depth (4) Tsoil1_SCR C Soil temperature for upper 8 cm layer (1) Tsoil2_SCR C Soil temperature for upper 8 cm layer (2) T_Soil_AVG_SCR C Soil temperature for upper 8 cm layer (average) T_soil_AVG_Diff_SCR C Change in soil temperature for upper 8 cm layer co2_mean_ scr agc + diags ppm Carbon dioxide concentration co2_mean(1) scr agc + diags mg m-3 Screened carbon dioxide concentration H2O_IRGA g m-3 Specific humidity CO2_24.5m_LI-840 ppm Carbon dioxide concentratin Wndspeed CSAT3_SCR m s-1 Wind speed Wind_Direction_SCR deg Wind direction ustar_SCR m s-2 Friction velocity RF_SCR_calibrated_ mm Rainfall ΔSCO2_SCR µmol m-2 s-1 Carbon dioxide storage flux Windspeed_SCR m s-1 Screened windspeed Soil Heat Flux_AVG_1_4_scr W m-2 G_scr W m-2 SM-1_0.04H_scr %_vol_wtr Vol. soil moisture content at 4 cm depth SM2_0_0.3_scr %_vol_wtr Vol. soil moisture content at 0-30 cm depth SM3_0.28_0.58_scr %_vol_wtr Vol. soil moisture content at 28-58 cm depth SM4_183-213_scr %_vol_wtr Vol. soil moisture content at 183-213 cm depth SM5_58_88_scr %_vol_wtr Vol. soil moisture content at 58-88 cm depth SM6_88_119_scr %_vol_wtr Vol. soil moisture content at 88-119 cm depth SM7_118-149__scr %_vol_wtr Vol. soil moisture content at 118-149 cm depth PAR_AUX_total_scr µmol m-2 s-1 Photosynthetically active radiation PAR_dif_scr µmol m-2 s-1 Photosynthetically active radiation PAR_dir_scr µmol m-2 s-1 Photosynthetically active radiation VPD_scr kPa Vapor pressure deficit T_hmp_bad 1_yes_0_no Air temperature flag RH_hmp_bad 1_yes_0_no Relative humidity flag
