Assessment of MISR and MODIS cloud top heights through inter-comparison with a back-scattering lidar at SIRTA

open access: yes, 2004
One year of back-scattering lidar cloud boundaries and optical depth were analysed for coincident inter-comparison with the latest processed versions of the NASA-TERRA MISR stereo and MODIS CO2-slicing operational cloud top heights. Optically thin clouds

Mapping arboretum research: Trends, gaps, and opportunities for biodiversity conservation, society, and climate resilience

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Arboreta bridge people and nature while conserving tree biodiversity, supporting climate resilience, and advancing environmental education. This study maps over a century of available and indexed arboretum research, uncovering trends, knowledge gaps, and opportunities for collaboration.

Stratospheric and tropospheric seasonality and its implications for observation requirements in numerical weather prediction

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Daily time series of zonal‐mean zonal wind (m·s−1) at 10 hPa and 60° N from 1950 to 2021 from the ERA5 reanalysis. This shows huge variability in some seasons and very little in others. We provide evidence that high‐level observations, radiosonde and satellite, are more important during the extended winter season with its very large variability ...

Exploiting Aeolus winds in a regional numerical weather prediction model

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
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 ...

Comparison of 2nd generation LiDAR wind measurement technique with CFD numerical modelling

open access: yes, 2012
With the rapid increase in both on and offshore wind turbine deployment there is a requirement for a better understanding of the flow field in which such devices are deployed.

An assessment of the use of airborne LiDAR for estimating growth of Sitka spruce (Picea sitchensis) plantation forestry at Kielder Forest, UK [PDF]

open access: yes, 2007
A growing need exists for the collection of accurate and up-to-date information on forest growth rates for management purposes. Recent studies indicate that airborne laser scanning (ALS) offers a quicker and more cost-effective approach than the ...

Towards improving Arctic mixed‐phase cloud representation in the ECMWF model using MOSAiC observations

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Abstract The presence of Arctic clouds plays a crucial role in the evolution of the surface temperature of Arctic sea ice. However, large biases in cloud representation remain in state‐of‐the‐art weather and climate models. In this study, we use observational data from the one‐year Arctic ship campaign Multi‐disciplinary drifting Observatory for the ...

Evaluating anisotropy‐based Monin–Obukhov similarity theory over canopies and complex terrain

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
This study shows that an anisotropy‐based generalization of Monin–Obukhov surface‐layer scaling (SC23) applies readily across a wide range of atmospheric conditions with variable terrain, canopies, and land‐cover complexity. This work focuses on the scaling of velocity variances for 7 years at the 47 sites in the National Ecological Observation Network
