What can this source tell us—and what can it not?

These values are MERRA-2 climate reanalysis model output, not rain-gauge measurements. They are useful for reading trends, but local accuracy is affected by model biases and by how complex terrain is represented within a grid cell. Sanad samples the roughly 0.5° monthly grid at each governorate centroid; this is not a spatial average of the governorate.
