NADP Precipitation Sampling Station
Problem statement
For the last 40 years a network of automated precipitation sampling devices has been operating across North America, monitoring weekly for changes in atmospheric pollutants by collecting weekly precipitation samples. Of the over 300 stations in the network, 50% are operating with aging Aerochem samplers from the 1980’s that are outdated and experience frequent malfunctions [1]. With so many precipitation sampling stations present throughout this network, these frequent malfunctions create many problems for both the technicians that collect the samples and the scientists who rely on the samples for research purposes. Modern precipitation samplers with upgraded capabilities exist, but their high price tags make them unreasonable investments [2]. A complete redesign of the sampler would be expensive and require a substantial amount of time to make a single prototype. In addition, a new sampler may cause a source of error in the experiment which has been recording data using the same sampler for the past 40 years. The best solution is to upgrade the aging components of the existing samplers, like the motor box, sensors, and clutch unit. This solution will produce a fleet of robust precipitation samplers to last the next 40 years, while cutting costs by changing only what is necessary.
