Abstract: In-situ meteorological observations have been collected for over 100 years and have demonstrated their critical use in forecasting, climatology, numerical modeling, and research applications. As detail and precision of output variables (e.g., forecasted air temperature) increases in end-user products, knowledge of the variability of input measurements can lead to a better understanding of implications from finer scale output errors of the variables. This study shows various examples temporal, spatial, and instrumental variability of in-situ observations of meteorological, hydrological, and atmospheric sensors. The impacts from aggregating sensor accuracy, spatial variability, and instrument variability is presented for consideration. Examples are shown of how small errors in a single measurement can manifest larger impacts on other variables and/or calculations.
