the samples were analyzed for 2 h and 18 o using a picarro l2130‐i isotopic water vapor analyzer with a precision of 0.5‰ for 2 h and 0.2‰ for 18 o. the chemcorrect software (picarro, 2010) was used to check the samples for organic contamination. samples that showed evidence of contamination were excluded from data analysis.
atmosphere is an international, peer-reviewed, open access journal of scientific studies related to the atmosphere published monthly online by mdpi.the italian aerosol society (ias) and working group of air quality in european citizen science association (ecsa) are affiliated with atmosphere and their members receive a discount on the article processing charges.
leaf-cutter ants are dominant herbivores that disturb the soil and create biogeochemical hot spots. we studied how leaf-cutter ant atta cephalotes impacts soil co 2 dynamics in a wet neotropical forest. we measured soil co 2 concentration monthly over 2.5 years at multiple depths in nonnest and nest soils (some of which were abandoned during the study) and assessed co 2
the water content was monitored over time, using a capacitive sensor (diviner 2000®, sentek pty ltda., australia) and access pipes installed, in each sub-subplot, up to 0.90 m of depth and 0.10 m from the rows of the species. the sensor was calibrated locally according to araújo primo et al. (2015), and monitoring was done every two days
in this review, the application of the photoacustic spectroscopy (pas) is presented as an option to evaluate the quality of food. this technique is a type of spectroscopy based on photothermal phenomena, which allow spectroscopic studies. according to the literature review, it was found that its application is increasing in several countries. spectroscopic studies carried out by employing pas

measurements of vertical wind speed, air temperature and water vapor density carried out with sampling frequency of 10 hz in the iag usp micrometeorological platform located in the university of são paulo butantã campus at the top of 4-store iag building where a csat3 sonic anemometer campbell and gas analyzer licor were set
photothermal beam deflection. photothermal beam deflection is a well-established technique for measuring thermal diffusivity. a linear relationship that arises in this technique is that given by the phase lag of the thermal wave as a function of the distance to a punctual heat source when unidimensional heat diffusion can be guaranteed.
