Reallocating fossil subsidies via social assistance reduces poverty and preserves emissions cuts

Fossil fuel subsidies are widespread, regressive, and environmentally costly, yet abrupt removal can raise poverty. To identify a practical reform pathway, we evaluate the effectiveness of compensatory policies grounded in existing national social protection systems. We develop a...

Advancing boundary-layer physics via Doppler wind LiDAR dynamic-thermodynamic profiling

Simultaneous, high-resolution measurements of boundary-layer dynamics and thermodynamics remain a longstanding observational challenge. We present a Doppler wind LiDAR–based retrieval that derives virtual potential temperature from TKE-budget buoyancy residuals, enabling concurre...
