请问下文最后" that correct for the other sources of water loss.
Then exchanges with the atmosphere are calculated by finding the difference between the gains from rain,as measured (rather roughly) by rain gauges雨量测量器,and the losses by evaporation,measured with models that correct for the other sources of water loss.
不需要前面的意思,that correct for the other sources of water loss.”的意思~

通过大气蒸发的失水量是用模型来测量的,这种模型对其他形式的失水量测量同样适用.我觉得“ that correct for the other sources of water loss”的意思就是对测量其他形式的失水量也适用.
