The connection of different modifications of the method of linear integral representation is studied. Solutions of the related inverse problems based upon a ‘hybrid version of two approximations’ of the topography and geopotential fields enable more refined tuning of the method in solving the inverse problems of geophysics and geomorphology and more complete allowance for the a priori infor- mation about the surface elevation data and elements of anomalous fields. The technique for finding a stable approximate solution for the inverse problem of determining the mass distributions equivalent by the external gravitational (or any other potential) field is presented. The method is applied to study anomalous densities beneath one of the highest elevation Elysium Mons and deep Hellas basin on Mars. The results of the mathematical experiment are discussed.

Comprehensive data on natural hazards and their consequences are crucial for effective for risk assessment, adaptation planning, and emergency response. However, many countries face challenges with fragmented, inconsistent, and inaccessible data, particularly regarding local-scale events. To address this data gap in Russia, we developed an end-to-end processing pipeline that scrapes news from various online sources, ...

Cloud shadows lead to alternating light and dark periods at the surface, with
the most abrupt changes occurring in the presence of low-level forced cumulus clouds.
We examine multiyear irradiance time series observed at a research tower in a midlatitude

made at a similar tower in a tropical ...

We examine the physical and biological responses of forest canopies to step changes in light
caused by passing low cumulus clouds that intermittently block the direct solar beam. Using
data obtained at a tropical rainforest and at a midlatitude deciduous forest, we estimate the
course of sensible heat flux, net ecosystem exchange, evapotranspiration, and water-use efficiency in response ...

Addressing effects of environment on eddy-covariance flux estimates at a temperate sedge-grass marsh
Sergey N. Kivalov, Dušek J., Czerný R. et al., Boundary-Layer Meteorology 2023 Vol. 186 P. 217–250
We examined the net-ecosystem-exchange (NEE)-based annual carbon-balance estimates
obtained from eddy-covariance (EC) measurements at an unmanaged sedge-grass marsh
ecosystem (Tˇreboˇn, Czech Republic, 49°1′ N, 14°46′ E), seeking methods to improve the EC
measurements in inhomogeneous environment. The data filtering procedure was developed
using three thresholds: (a) a stationarity test; (b) a stability u∗-threshold; and (c) a high relative
humidity RH-threshold. ...

diagnosed net ecosystem exchange (NEE) and water-use efficiency (WUE) of a temperate broadleaf forest and a
tropical evergreen forest as they responded to natural fluctuating-light regimes. Here we ...

Carbon dioxide (CO₂) efflux from soil (or soil respiration, SR) is one of the most important yet variable characteristics of soil. When evaluating large areas, CO₂ efflux modeling serves as a viable alternative to direct measurements. This research aims to identify site-specific differences and their effects on empirical CO₂ efflux modeling. The experimental data from ...

Late Pleistocene transformation of European glacial landscapes is often narrowed down to the impact of
postglacial linear erosion. Yet in the marginal zone of MIS 6 glaciation extensive watersheds were protractedly
affected by the postglacial flattening in periglacial and interglacial conditions. Local sediment sinks such

Исследования выдающегося ученого античности М. С. Куторги в Беотии соответствовали передовому европейскому научному уровню середины XIX столетия.
Не в последнюю очередь этому способствовал «критический метод», который М. С. Куторга воспринял еще во время обучения в Дерпте, а затем и в Берлине. Главным
залогом успеха в исследовании Беотии можно считать обусловленный знакомством
с западной литературой по топографии Греции выбор ...
