Performance simulations for a spaceborne ozone lidar mission

Optics Express
The future range resolved spaceborne ozone differential absorption lidar (SODIAL) is expected to fill the current observation gap, especially in areas where in-situ observation and passive remote sensing are difficult. The spaceborne ozone lidar preparatory research mission (SOLPRM) proposed by the State Administration of Science, Technology, and ...

Airborne lidar reflectance measurements at 1.57 μm in support of the A-SCOPE mission for atmospheric CO₂ [PDF]

Atmospheric Measurement Techniques, 2009
The characteristics of the lidar reflectance of the Earth's surface is an important issue for the IPDA lidar technique (integrated path differential absorption lidar) which is the proposed method for the spaceborne measurement of atmospheric carbon ...

Investigating the Effects of Spatial Snow Water Equivalent Heterogeneity on Runoff Timing and Magnitude

Hydrological Processes, Volume 40, Issue 7, July 2026.
Processes (e.g., orographic enhancement, avalanches, wind redistribution) occur across varying scales (10–100 m, 100–1000 m, and above) that impact the heterogeneity of the seasonal snowpack. We directly inserted near peak lidar‐derived snow water equivalent data with differing resolutions and a constant volume of water into a hydrologic model.

Detecting Change in Forest Structure with Simulated GEDI Lidar Waveforms: A Case Study of the Hemlock Woolly Adelgid (HWA; Adelges tsugae) Infestation

Remote Sensing, 2020
The hemlock woolly adelgid (HWA; Adelges tsugae) is an invasive insect infestation that is spreading into the forests of the northeastern United States, driven by the warmer winter temperatures associated with climate change.

Exploiting Aeolus winds in a regional numerical weather prediction model

Quarterly Journal of the Royal Meteorological Society, Volume 152, Issue 778, July 2026 Part A.
Aeolus measured winds have proven to be beneficial for global models. However, demonstrating positive impact for limited‐area models has been a challenge so far. For the first time, we have demonstrated a statistically significant positive impact of Aeolus winds in a limited‐area model by using the 4DVar data assimilation technique and the most recent ...

Flood Inundation Modeling Using the Surface Water Ocean Topography Mission

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract Flood risk mapping requires detailed river bathymetry, yet these data are unavailable for most rivers. We propose a new algorithm to estimate river bathymetry from multitemporal observations of water height by the Surface Water and Ocean Topography (SWOT) mission.

Assimilation of Satellite‐Based Forest Biomass, Productivity and Leaf Area Index in a Global Land Model Incorporating Parameter Spatial Variations and Age Effects

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 7, July 2026.
Abstract Disturbances profoundly impact forest capacity for sequestering and storing carbon, and the recovery rates after disturbances vary geographically. Many terrestrial carbon models inadequately simulate the effects of forest disturbances on biomass due to their reliance on equilibrium assumptions, the absence of historical disturbance data, as ...

Adaptation and Response in Drylands: A Dryland Research Agenda and Campaign Strategy

Global Change Biology, Volume 32, Issue 7, July 2026.
The Adaptation and Response in Drylands (ARID) campaign was selected by NASA as a scoping study to develop a research agenda for a dryland field campaign. Here, we detail our ARID science research agenda and implementation plan that were developed based on an extensive community engagement effort in over 160 events with over a thousand scientists, land
