This paper presents the project Earth Cooling by Water Vapor Radiation, an observational programme, which aims at developing a database of spectrally resolved far infrared observations, in atmospheric dry conditions, order to validate radiative transfer models and test quality water vapor continuum line parameters. The provides very first set far‐infrared spectral downwelling radiance measurements, are complemented with Raman Lidar‐derived temperature profiles.
Abstract Soot particles form during combustion of carbonaceous materials and impact climate air quality. When freshly emitted, they are typically fractal-like aggregates. After atmospheric aging, can act as cloud condensation nuclei, water or evaporation restructure them to more compact aggregates, affecting their optical, aerodynamic, surface properties. Here we survey the morphology ambient soot from various locations different environmental aging conditions. We used electron microscopy...
The paper presents a novel methodology to retrieve the foreign-broadened water vapor continuum absorption coefficients in spectral range 240 590 cm -1 and is first estimation of coefficient at wave numbers smaller than 400 under atmospheric conditions.The derivation has been accomplished by processing suitable set emitted radiance observations obtained during March 2007 Alps campaign ECOWAR project (Earth COoling WAter Radiation).It shown that, 450 600 , our findings are good agreement with...
Considering the scarce number of studies investigating oxidative potential PM2.5 in Italy, a measurement campaign was conducted from February 2020 to October coastal semi-rural site Basilicata (Southern Italy) with goal characterize fine fraction ambient particulate matter (PM) and investigate its chemical toxicological properties, by means potential. Different instruments such as an automatic low-volume sampler, aethalometer optical particle counter, were employed for mass concentration,...
The international experiment called the European Aqua Thermodynamic Experiment (EAQUATE) was held in September 2004 Italy and United Kingdom to validate satellite Atmospheric Infrared Sounder (AIRS) radiance measurements derived products with certain groundbased airborne systems useful for validating hyperspectral sounding observations. A range of flights over land marine surfaces were conducted coincide overpasses AIRS instrument on Earth Observing System platform. Direct evaluation using...
Initial measurements of black carbon (BC) content at both 880 and 370 nm, obtained in two sites southern Italy by an aethalometer, have been analyzed. The are located the same region (Basilicata), but affected different emission sources. In one case main source BC is related to vehicular traffic from a nearby freeway. Data were collected, although not continuously, during 2008, 2009 2010. second case, fresh crude-oil pre-treatment plant continuously burns petroleum-derived products, thus...
We evaluate the spectral quality, radiometric noise, and retrieval performance of a Fourier transform infrared spectrometer, which has been developed for recording spectrally resolved observations in region spectrum is important both science Earth's climate applications, such as remote sensing temperature atmospheric gas species. This extends from 100 to 1600 cm(-1) encompasses two fundamental, rotation vibration, absorption bands water vapor. The instrument customized version Bomem AERI...
Observations of very low amounts precipitable water vapor (PWV) by means the Ground‐Based Millimeter wave Spectrometer (GBMS) are discussed. Low column (between 0.5 and 4 mm) typical high mountain sites polar regions, especially during winter, difficult to measure accurately because lack sensitivity conventional instruments such PWV contents. The technique used involves measurement atmospheric opacity in range between 230 280 GHz with a spectral resolution GHz, followed conversion using...
Abstract. Physical and optical properties of atmospheric aerosols collected by using a high resolution (1.5 nm) spectroradiometer (spectral range 400–800 nm), 13-stage Dekati Low Pressure Impactor (size 30 nm–10 μm), an AE31 Aethalometer (7 wavelenghts from 370 nm to 950 have been examined in semi-rural site Southwest Italy (Tito Scalo, 40°35' N, 15°41' E, 750 m a.s.l.). In particular, daily averaged values AOD Ångström turbidity parameters radiometric data together with mass-size...
Ground-based Fourier Transform Spectrometer observations in the infrared, acquired during Italian phase of EAQUATE campaign, have been considered this study and compared to calculations. Synthetic spectral radiances obtained using 2000 2004 releases 2006 upgrade HITRAN databases. It has found that synthetic radiance computations fit data quite well, even though goodness depends on database. Differences residual behaviour appear be mostly localized long-wave side Earth emission spectrum, i.e....
Abstract. A novel approach for the analysis of aerosol absorption coefficient measurements is presented. 7-wavelenghts aethalometer has been employed to identify brown carbon (BrC) and black (BC) detect organic (OC) in fine atmospheric aerosols (PM2.5). The Magee Aethalometer estimates BC content particulate by measuring light attenuation accumulated on a quartz filter, at standard wavelength λ = 0.88 μm. known algorithm based hypothesis mass inversely proportional wavelength. new developed...
A short-term intensive multi-instrumental measurement campaign (Integrated Measurements of Aerosol in Agri valley - IMAA) was carried out near the largest European oil and gas pre-treatment plant (Centro Olio Val d'Agri COVA) a populated area, where, so far, ample characterization aerosol loading is missing. As such, between 2 17 July 2013, using number instruments analyses were on physical, chemical, morphological optical properties at this distinctive site, both ground over atmospheric...
