“…These cross-scale modeling results are corroborated by observational 114 studies that have found decreases in surface temperature correlated with increasing spatial 115 extent of irrigated agriculture in California (Bonfils and Lobell 2007) and the High Plains 116 aquifer of the Southern Great Plains (Mahmood et al 2013). 117…”

1In the United States, irrigation represents the largest consumptive use of freshwater and 2 accounts for approximately one-third of total water usage. Irrigation impacts soil moisture 3 and can ultimately influence clouds and precipitation through land-planetary boundary 4 layer (PBL) coupling processes. This study utilizes NASA's Land Information System (LIS) 5 and the NASA Unified Weather Research and Forecasting (NU-WRF) framework to 6 investigate the effects of drip, flood, and sprinkler irrigation methods on land-atmosphere 7 interactions, including land-PBL coupling and feedbacks at the local scale. Five-year 8 irrigated LIS spinups were used to initialize two-day, 1 km WRF forecasts over the Central 9Great Plains in a drier than normal (2006) and a wetter than normal year (2008). The 10 offline and coupled simulation results show that regional irrigation impacts are sensitive to 11 time, space and method, and that irrigation cools and moistens the surface over and 12 downwind of irrigated areas, ultimately resulting in both positive and negative feedbacks 13 on the PBL depending on the time of day and background climate conditions. Furthermore, 14 the results portray the importance of both irrigation method physics and correct 15 representation of several key components of land surface models including accurate and 16 timely land cover and crop type classification, phenology (greenness), and soil moisture 17 anomalies (through an LSM spinup) in coupled prediction models. 18 3

“…For example, from 1950 to 2010, the amount of corn harvested annually in the Corn Belt increased by 400%, from 2 billion to 10 billion bushels (National Agricultural Statistics Service, ) (Figure b and Movie S1). These large‐scale land use modifications likely affected atmospheric processes, as changes in rain‐fed and irrigated cropland have previously been shown to influence climatic variables such as evapotranspiration (Adegoke et al, ; Cook et al, ; Harding & Snyder, ; Huber et al, ; Im, Marcella, et al, ; Jin & Miller, ; Lo & Famiglietti, ; Mahmood et al, ; Ozdogan et al, ; Qian et al, ; Wei et al, ), temperature (Adegoke et al, ; Alter et al, ; Barnston & Schickedanz, ; Cook et al, ; Harding & Snyder, ; Haugland & Crawford, ; Huber et al, ; Im, Marcella, et al, ; Jin & Miller, ; Kueppers et al, ; Mahmood et al, ; Mueller et al, ; Qian et al, ), humidity (Adegoke et al, ; Cook et al, ; Harding & Snyder, ; Haugland & Crawford, ; Huber et al, ; Lo & Famiglietti, ; Mahmood et al, ; Qian et al, ), and precipitation (Alter et al, ; Barnston & Schickedanz, ; Cook et al, ; DeAngelis et al, ; Harding & Snyder, ; Huber et al, ; Im, Marcella, et al, ; Lo & Famiglietti, ; Mueller et al, ; Qian et al, ; Stidd, ; Wei et al, ). Given these established linkages, one would expect that these historical increases in crop production have impacted regional climate in the central United States.…”

Both land use changes and greenhouse gas (GHG) emissions have significantly modified regional climate over the last century. In the central United States, for example, observational data indicate that rainfall increased, surface air temperature decreased, and surface humidity increased during the summer over the course of the twentieth century concurrently with increases in both agricultural production and global GHG emissions. However, the relative contributions of each of these forcings to the observed regional changes remain unclear. Results of both regional climate model simulations and observational analyses suggest that much of the observed rainfall increase—as well as the decrease in temperature and increase in humidity—is attributable to agricultural intensification in the central United States, with natural variability and GHG emissions playing secondary roles. Thus, we conclude that twentieth century land use changes contributed more to forcing observed regional climate change during the summer in the central United States than increasing GHG emissions.

“…Hydrological processes play an important role in land surface models (LSMs) (Crossley et al., 2000; Mahmood et al., 2013; Pitman, 2003; Seneviratne et al., 2010; Wei & Dirmeyer, 2010; Yeh et al., 1984). In particular, the ability to simulate runoff is a useful diagnostic for the hydrological cycle and other surface parameterizations (Kuhl & Miller, 1992).…”
