We demonstrated that a regression - based statistical correction for the proportion of the students in each teacher's class that are English - language learners, have education disabilities, are from low - income families, and so forth, wrings most of the bias out of classroom observations.

In this case, there has been an identification of a host of small issues (and, in truth, there are always small issues in any complex field) that have involved the fidelity of the observations (the spatial coverage, the corrections for known biases), the fidelity of the models (issues with the forcings, examinations of the variability in ocean vertical transports etc.), and the coherence of the model - data comparisons.

Progress in the longer term depends on identifying and correcting model biases, accumulating as complete a set of historic observations as possible, and developing improved methods of detection and correction of observational biases.»

He also presented an example of the application of bias correction to individual meteorological variables prior to the formulation of the index based on climate simulations, and showed that the values obtained for the index fitted quite nicely the observations.

NASA GISS obtain much of their temperature data from the NOAA who adjust the data to filter out primarily time - of - observation bias (although their corrections also include inhomogeneities and urban warming - more on NOAA adjustments).

The assimilation methodology is 24 - hour 4D - Var analysis, with variational bias correction of surface pressure observations.

In locations where the difference between observations and RCMs is large, bias correction tends to inflate the magnitude of projected extremes.

Topics include bias correction, non-linear observation operators and correlated obs errors and how to treat them in data assimilation systems.

ECMWF as the Entrusted Entity for the Copernicus Climate Change Service (C3S) invites tenders for a service related to bias correction of observations in support of climate services development.

As the trend in the US rural stations, which at least until very recently employed these min / max stations, has been from early evening observation (5 pm or 7 pm in most of the sources I've found) to early morning observation (usually 7 am), this has been presumed to put an artificial cooling bias into the temperature record, so a net positive, and increasing as more stations have been converted, correction has been added to the raw data.

Am I correct, that in this case «raw» excludes corrections for time of observation bias, which the NOAA data includes?

The reason this choice matters is that this bias correction will be applied to the 21st century simulations, and the bias corrections are useless if you are merely correcting for multidecadal variability that is out of phase with the observations.
