The Normalized Difference Vegetation Index (NDVI) is widely used for Leaf Area Index (LAI) estimation. It is well documented that the NDVI is extremely subject to the saturation problem when LAI reach...
Chemical processes in the ocean and at its interfaces with the atmosphere and the seafloor play a major role in regulating global biogeochemical cycles. Predicting the impact of human disturbances on ...
Bio-optical measurements at 50 stations in the Gulf and Estuary of Saint Lawrence were carried out over three major field campaigns in 1999, 2000, and 2001. These campaigns were performed over diffe...
This work demonstrates an example of the importance of an adequate method to sub-sample model results when comparing with in situ measurements. A test of model skill was performed by employing a point...
The temperature-sensitive lipids, long chain alkenones (LCAs), are considered to be a powerful paleothermometer in deciphering the variability of sea surface temperature (SST) through time. Recent stu...
This study was aimed to investigate the concentration of hydrogen peroxide (H2O2), nitric acid (HNO3) and reactive nitrogen (NOy) at three sites in Southern Taiwan during 2003–2004. The mean H2O2 con...
Volcanic emissions from the Eyjafjallajökull volcano eruption on the Southern fringe of Iceland in April 2010 were detected at the Global Atmosphere Watch (GAW) station Zugspitze/Hohenpeissenberg...
The Finnish Meteorological Institute (FMI), together with The Energy and Resources Institute of India (TERI), contributed to the European Integrated project on Aerosol Cloud Climate and Air Quality In...
The first ground-based remote sensing measurements of the column averaged volume mixing ratio of CO2 (XCO2) in tropical South America have been obtained at Paramaribo, Suriname (5.8° N, 55.2° W). The ...
Processes occurring in the tropical upper troposphere (UT), the Tropical Transition Layer (TTL), and the lower stratosphere (LS) are of importance for the global climate, for stratospheric dynamics an...
Discrete in situ atmospheric measurements of molecular iodine (I2) were carried out at Mace Head and Mweenish Bay on the west coast of Ireland using diffusion denuders in combination with a gas chroma...
Turbulence was measured in situ within shoals of juvenile perchPerca fluviatiliswith a self-contained autonomous microstructure profiler near an artificial reef in Lake Constance, Germany. Depth-avera...
Continuous high-frequency measurements of atmospheric molecular hydrogen have been made at Mace Head atmospheric research station on the west coast of Ireland from March 1994 to December 2008. The pre...
Volume mixing ratio (vmr) vertical profiles of hydrogen chloride (HCl) are retrieved from in situ measurements performed by a balloon-borne infrared tunable diode laser absorption spectrometer (SPIRAL...
Subsurface parameters, such as hydraulic head, often vary markedly with depth in fine-grained glacial sediments, but sensors placed in vertical boreholes are poorly suited to resolve these variation...
