    All transmissions from GMS-5 are no longer received at NIWA’s satellite reception station in Wellington. We are working on an alternative data feed and will be able to bring back these images later this year. Once we start receiving data again, it will then be calibrated, re-mapped onto standard map projections, and archived.
