Site ID: BR-Ma2

Site Name: Manaus - ZF2 K34

Variables: Air Temperature; Barometric pressure; Relative humidity; Vapor Pressure Deficit

Date Range: Jan. 1, 1850 - Jan. 1, 2100

Description: Historical and projected output data variables extracted and derived from Community Earth System Model 2 (CESM2) runs from the Coupled Model Intercomparison Project Phase 6 (CMIP6) archive. CESM2 is a fully coupled Earth system model used in simulations of Earth's past, present, and future climates (Danabasoglu et al., 2020). Variables in this dataset are in six-hourly resolution, and include air temperature (both in K and ℃), specific humidity (kg kg-1), air pressure (Pa), relative humidity (%), and vapor pressure deficit (kPa). CESM2 was the only CMIP6 model that provided VPD at the high temporal resolution required for this analysis. Data are included in .csv files, and the text file CESM2-CMIP6_forcing_K34-Manaus_headers.txt provides descriptions of data file headers.

Methods Description: The data variables extracted are at a six-hourly resolution (at 2 am, 8 am, 2 pm, and 8 pm local time each day), and include instantaneous air temperatures, air pressure, and specific humidity, from historical and four SSP scenarios (i.e., SSP126, SSP245, SSP370, and SSP585). These CESM2 forcing data (member ID r11i1p1f1) were extracted at the location of K34 site for the period of 1980-2100. Corresponding six-hourly instantaneous VPD was calculated using air temperature, air pressure, and specific humidity following the Clausius–Clapeyron equation.
