🌊💨 How reservoirs “breathe”: floating-chamber observations at the Rur reservoir track CO₂ and CH₄ fluxes across seasons. CO₂ can shift from sink to source, while CH₄ is emitted throughout the year — showing why year-round monitoring matters.

What would you track first with global near-real-time water storage data — drought, floods, groundwater depletion, or something else?

🍎⚖ #DETECTapple: Tiny gravity changes, huge insight! @aquasong.bsky.social studies how iGrav043 near Bonn tracks water storage, incl. water taken up by trees 🌱💧.
A 2-yr iGrav vs eCLM comparison agrees. GRACE-FO assimilation did not improve the match.
