1/2/2023 0 Comments Daily rainfall totals![]() ![]() The first 24 hours are often preliminary and can occasionally change the next day as more data/confidence is displayed in estimates. This data set utilizes a multisensor approach to estimate precipitation including radar, satellite, and rain gauge data. We utilize the National Weather Service’s Quantitative Precipitation Estimates (Figure 4) to help fill in the gaps between our stations and to paint the bigger picture. While there are many Kansas Mesonet stations across the state, resolution is still too coarse to build an interpolated map with our observations alone. Altershield and rain gauge oriented in proximity to the Cheyenne station. This increases catch and accuracy during wind events. As a result of this turbulence, precipitation will fall into the gauge instead of blowing across it. This screen consists of metal sleeves that create a ring that disrupts the wind flow in and around the rain gauge. Surrounding all rain gauges at Mesonet tower stations is an altershield, also called a wind screen (Figure 3). Most commonly utilized data consists of the five minute, hourly, and daily accumulation - the total number of tips measured over the time period of interest. While we collect up to one minute resolution precipitation data - these are typically used for research and verification. Hydrological Services TB3 siphon tipping bucket rain gauge (Source: ).ĭata is collected across the Kansas Mesonet at several different frequencies. Texas Electronics 525 model (Source: ).įigure 2. Some have a combination of the two.įigure 1. Due to battery restrictions, cost, clogging, and sensor issues - the network primarily uses the TE525 model at most stations. Between 2009 - 2018, new stations had the Hydrological Services TB4 gauge which was essentially the same, but consisted of a heating mechanism to measure snow. These are also both primarily warm season tools that measure in 0.01 inch increments. The other gauge commonly used across the network is the Hydrologic Services TB3 siphon tipping bucket gauge. The most prominent gauge is the Texas Electronics 525 (TE525) model with a six inch opening (Figure 1). Xu (2012) - Homogenization of Canadian in-situ precipitation data, Final Report of Contract KM040-09-1134.The Kansas Mesonet utilizes two different styles of rain gauges on the network. A total of 2146 stations were processed their record lengths vary from 3 to167 years. The processing includes inspection and adjustment using quality control procedures customized for producing gridded datasets, including: (1) conversion of snowfalls to their water equivalents (2) corrections for gauge undercatch and evaporation due to wind effect, for gauge specific wetting loss, and for trace precipitation amount (same as in Mekis and Vincent, 2011) (3) treatment of flags (e.g. This dataset contains adjusted daily rainfall (R) and snowfall (S) data from all Canadian stations reporting rainfall and snowfall for which we have metadata to do the adjustments.
