The Japan Meteorological Agency launched a geostationary weather satellite called Himawari-8 in October 2014. “Himawari” means sunflower, and the name has been given to a series of satellites that we can look forward to in coming years. “Geostationary” means the satellite rotates “in sync” with the Earth, always above the same point over the equator.
A satellite receiver ("dish"), for improved reception of data from polar-orbiting weather satellites, was installed at MetService Head Office in Kelburn in February 2013.
Polar-orbiting weather satellites yield rich information about the atmosphere, valuable for New Zealand weather forecasting. Benefits of faster access to more data, and sharper identification tools, include:

In this blog post we’ll look at some interesting small-scale cloud structures around the country on this day.
