Data for the manuscript "OpenMesh: Wireless Signal Dataset for Opportunistic Urban Weather Sensing in New York City" (Jacoby et al., accepted for publication in Earth System Science Data). The OpenMesh dataset comprises received signal level (RSL) measurements from over 103 wireless links operated by the NYC Community Mesh network. These opportunistic link observations, captured at one-minute intervals, enable urban weather sensing without dedicated instrumentation. This dataset is the result of a collaboration between the WiMNet Lab at Columbia University, the CellEnMon Lab at Tel-Aviv University, and the NYC Mesh community. We gratefully acknowledge NYC Mesh for granting access to the network hardware.
