Jovian Infrared Auroral Mapper

Jovian Infrared Auroral Mapper (JIRAM) is an instrument on the Juno spacecraft in orbit of the planet Jupiter.

[1] The primary goal of JIRAM is to probe the upper layers of Jupiter's atmosphere down to pressures of 5–7 bars (72–102 pound/square inch) at infrared wavelengths in the 2–5 μm interval using an imager and a spectrometer.

[2] In particular it has been designed to study the dynamics and chemistry in the atmosphere, perhaps determining the how Jovian hot spots form.

[14] By this time Juno had completed 10 close passes for science observations, since arriving in Jupiter's orbit on July 4, 2016.

[15] Various results, including a 3-D movie a flyover of the north pole of Jupiter with JIRAM data were released at the European Geosciences Union General Assembly in April 2018.
