Ground measurements of thermal infrared emissivities terrestrial surfaces are required to derive accurate temperatures from radiometric measurements, and also apply validate emissivity models using satellite sensor observations. This paper focuses on the demanding aspects that involved in field measurement box method a hand-held radiometer. Measuring conditions can be hampered by external factors such as wind solar irradiance. increase time spent campaign but, most importantly, it cause...
Thermal infrared (TIR) emissivities of soils with different textures were measured for several soil moisture (SM) contents under controlled conditions using the Box method and a high-precision multichannel TIR radiometer. The results showed common increase emissivity SM at water lower than field capacity. However, this dependence is negligible higher contents. highest variations observed in sandy soils, particularly 8-9-μm range due to adhering grains decreasing reflectance quartz doublet...
This research analyzes how enzymatic and microbiological soil properties relate to site index (SI) forest maturity (stand age) in Pinus nigra (P. nigra) even-aged forests. The parameters selected for multivariate analysis were four activities (β-glucosidase, urease, dehydrogenase, alkaline phosphatase), two (microbial biomass C basal respiration), five physicochemical (TOC, N, P, pH, water content). We used LiDAR, the digital elevation model, terrain model obtain a result dominant height...
Abstract. The imbalance in the surface energy budget, when using eddy-covariance techniques to measure turbulent fluxes, is still an unresolved problem. Important progresses have been reported recent years identifying potential reasons for this lack of balance closure. In paper we focus on data collected a FLUXNET boreal forest site Sodankylä, Finland. Using one month half-hourly data, average Energy Balance Ratio (EBR) 0.72 obtained. inclusion heat storage terms budget yields improvement...
One of the missions being planned by European Space Agency (ESA) within framework its Earth Observation Programme is Processes Research Imaging Mission (PRISM). The PRISM instrument consists a thermal sensor whose main objective to retrieve accurate land surface temperatures (LST) and band positions are 3.5–4.1 μm, 8.1–9.5 10.3–11.3 11.5–12.5 μm. We have studied optimal design this LSTs. First, we analyzed several emissivity‐temperature separation methods (part 1) atmospheric emissivity...
In semi-arid regions, afforestation with fast-growing species cultured low irrigation can be an effective approach for environmental protection. An experiment was conducted to evaluate the stem biomass production of Paulownia in a climate and clay soils under contrasting low-irrigation fertilization treatments. The at stand level estimated by applying allometric equations fitted sample resprouts inventory data. results show that improved when either or fertilizer added, but combination...
Treatments involving vegetation thinning have become more frequent in Mediterranean forest ecosystems. Under extreme climate conditions, this practice can affect the balance between physicochemical, microbiological and biochemical soil properties, modifying quality ability of these ecosystems to regenerate. The aim study was use principal component analysis (PCA) develop a multivariable soil‐quality index (SQI) applicable Cuenca mountain range central‐eastern Spain. To achieve this, seven...
Forest inventories are essential to accurately estimate different dendrometric and forest stand parameters. However, classical time consuming, slow conduct, sometimes inaccurate costly. To address this problem, an efficient alternative approach has been sought designed that will make type of field work cheaper, faster, more accurate, easier complete. The implementation concept required the development a specifically software called "Artificial Intelligence for Digital (AID-FOREST)", which is...
Abstract. Estimates of surface actual evapotranspiration (ET) can assist in predicting crop water requirements. An alternative to the traditional crop-coefficient methods are energy balance models. The objective this research was show how temperature observations be used, together with a two-source model, determine use throughout different phenological stages grown. Radiometric temperatures were collected sorghum (Sorghum bicolor) field as part an experimental campaign carried out Barrax,...
Abstract. Information about forest background reflectance is needed for accurate biophysical parameter retrieval from canopies (overstory) with remote sensing. Separating under- and overstory signals would enable more modeling of carbon energy fluxes. We retrieved values the normalized difference vegetation index (NDVI) understory multi-angular Moderate Resolution Imaging Spectroradiometer (MODIS) bidirectional distribution function (BRDF)/albedo data (gridded 500 m daily Collection 6...
Soil moisture and ocean salinity at surface level can be measured by passive microwave remote sensing L‐band. To provide global coverage data of soil with three‐day revisit time, the Earth Explorer Opportunity Mission SMOS (Soil Moisture Ocean Salinity) was selected ESA (European Space Agency) in May 1999. SMOS' single payload is a Y‐shaped 2‐D aperture synthesis interferometric radiometer called MIRAS (Microwave Imaging Radiometer Aperture Synthesis). presents some particular imaging...
Sea surface salinity can be measured by passive microwave remote sensing at L-band. In May 1999, the European Space Agency (ESA) selected Soil Moisture and Ocean Salinity (SMOS) Earth Explorer Opportunity Mission to provide global coverage of soil moisture ocean salinity. To determine effect wind on sea emissivity, ESA sponsored Wind Experiment (WISE 2000). This paper describes field campaign, measurements acquired with emphasis in radiometric L-band, their comparison numerical models,...
Forest fires affect the natural cycle of vegetation, and structure functioning ecosystems. As a consequence defoliation vegetation mortality, surface energy flux patterns can suffer variations. Remote sensing techniques together with balance modeling offer opportunity to explore these changes. In this paper we focus on Mediterranean forest ecosystem. A fire event occurred in 2001 Almodóvar del Pinar (Spain) affecting pine shrub area. two-source approach was applied set Landsat 5-TM 7-EMT+...
