The observation of gaseous giant planets is of high scientific interest.Although they have been the targets of several spacecraft missions, there stillremains a need for continuous ground-based observations. As their atmospherespresent fast dynamic environments on various time scales, the availability oftime at professional telescopes is neither uniform nor of sufficient durationto assess temporal changes. However, numerous amateurs with small telescopes(of 15-40 cm) and modern hardware and software equipment can monitor thesechanges daily (within the 360-900nm range). Amateurs are able to trace thestructure and the evolution of atmospheric features, such as majorplanetary-scale disturbances, vortices, and storms. Their observations providea continuous record and it is not uncommon to trigger professional observationsin cases of important events, such as sudden onset of global changes, stormsand celestial impacts. For example, the continuous amateur monitoring has ledto the discovery of fireballs in Jupiter's atmosphere, providing informationnot only on Jupiter's gravitational influence but also on the properties andpopulations of the impactors. Photometric monitoring of stellar occultations bythe planets can reveal spatial/temporal variability in their atmosphericstructure. Therefore, co-ordination and communication between professionals andamateurs is important. We present examples of such collaborations that: (i)engage systematic multi-wavelength observations and databases, (ii) examine thevariability of cloud features over timescales from days to decades, (iii)provide, by ground-based professional and amateur observations, the necessaryspatial and temporal resolution of features that will be studied by theinterplanetary mission Juno, (iv) investigate video observations of Jupiter toidentify impacts of small objects, (v) carry out stellar-occultation campaigns.
