photosphere and chromosphere
Evidence of ubiquitous Alfvén pulses transporting energy from the photosphere to the upper chromosphere
... Discussion 2). The exact contribution of these Alfvén pulses to the global upper chromospheric heating needs to be further studied by applying ASDA to observational data with higher spatial and temporal resolutions. ...
