Hello, we procure the SO2 forecast from NASA and their GOES-5 model, that is updated once every 12 hours, provides 3 hours step interval and only renders with 22km resolution. Due to that, that forecast could be inaccurate on such 'small' levels as the volcanic fissures. We've also received a feedback, that 5+ppm units should be more comprehensible, than current ug/m3. What's your take on it? I hope you're safe. Michael
