Standard "wet buckets" for collecting rain and snowfall. The sensor (a) is triggered through rain falling on its grid. This in turn operates the motor for the lid (b), which swings it off of the wet bucket (c), and onto the other side of the sampler (d), thus opening the wet bucket. This remains open until the storm event is over. The lid returns to its original position over the wet bucket (adapted from Lippincott et al. 1982).
