  "textContent": "Extending the spatial coverage of a reference pressure network. Particular embodiments described herein include machines that initially determine that an estimated position of a mobile device resides outside a coverage area of a network of reference pressure sensors. Reference-level pressures are determined using measurements of pressure from the network of reference pressure sensors. A time interval and a plurality of wind speeds and corresponding wind directions are used to determine an adjusted location for each reference pressure sensor of the network. The adjusted location and the reference-level pressure for each reference pressure sensor are used to determine a pressure pattern, which is used to determine a reference-level pressure value for the estimated position of the mobile device. The reference-level pressure value is used for calibrating a pressure sensor of the mobile device, or for estimating an altitude of the mobile device for emergency response or navigation.",
