Ideally, if both observation and model simulation arenot biased, random errors will be minimized by theanalysis scheme, and there will be no artificial climatetrend in the reanalysis data.In reality, both observation and model are more orless biased. As the global observing system changesalong the time, the reanalysis homogeneity is hard tobe kept, even with fixed model and analysis scheme.
Features in the NASA MERRA reanalysis toDecrease the Side Effect of Observing System Incremental Analysis Updates (IAU) to slowly adjustthe model states toward the observed state. Adaptive Biases Correction to keep temporalhomogeneity in each observation type. Using homogenized radionsonde data fromHaimberger (2007).But the impact of the introductions of New ObservationPlatforms was not addressed.
