“…The Modern-Era Retrospective analysis for Research and Applications (MERRA) was intended to utilize satellite observations and improve representation of the hydrologic cycle [61]. The current MERRA-2 further incorporated assimilation of aerosol data and of station precipitation observations [62,63], which has led to it being used extensively for studies of wind and solar availability [64][65][66] as well as in studies of global hydrology [67]. The station precipitation data assimilated into MERRA-2 in the Indus basin region are from the Climate Prediction Center Unified Gauge-Based Analysis of Global Daily Precipitation (CPCU) [63].…”

A large population relies on water input to the Indus basin, yet basinwide precipitation amounts and trends are not well quantified. Gridded precipitation data sets covering different time periods and based on either station observations, satellite remote sensing, or reanalysis were compared with available station observations and analyzed for basinwide precipitation trends. Compared to observations, some data sets tended to greatly underestimate precipitation, while others overestimate it. Additionally, the discrepancies between data set and station precipitation showed significant time trends in such cases, suggesting that the precipitation trends of those data sets were not consistent with station data. Among the data sets considered, the station-based Global Precipitation Climatology Centre (GPCC) gridded data set showed good agreement with observations in terms of mean amount, trend, and spatial and temporal pattern. GPCC had average precipitation of about 500 mm per year over the basin and an increase in mean precipitation of about 15% between 1891 and 2016. For the more recent past, since 1958 or 1979, no significant precipitation trend was seen. Among the remote sensing based data sets, the Tropical Rainfall Measuring Mission Multi-Satellite Precipitation Analysis (TMPA) compared best to station observations and, though available for a shorter time period than station-based data sets such as GPCC, may be especially valuable for parts of the basin without station data. The reanalyses tended to have substantial biases in precipitation mean amount or trend relative to the station data. This assessment of precipitation data set quality and precipitation trends over the Indus basin may be helpful for water planning and management.

Energy storage needs for an Australian national electricity market grid without combustion fuels

Energy Storage

The opportunity to achieve a wind and solar energy only Australian national electricity market (NEM) grid is linked to the development of massive energy storage systems. Photovoltaic solar energy is unavailable nighttime and reduced when it is cloudy or raining. Wind energy also drops some days to zero, with similarly large fluctuations between maximum and minimum energy supplies. This fundamental aspect is being ignored when only trying to increase the nominal capacity of wind energy and solar photovoltaic facilities. The need for a massive energy storage system to properly use this increased capacity is highlighted by the high-frequency energy generation data by source that we show for the NEM that is covering most of South Australia, Victoria, Tasmania, New South Wales, and Queensland, with the only exception of Western Australia and the Northern Territory. This analysis highlights the present energy storage needs for a NEM wind and solar only. The nominal capacity of wind and solar, and the energy storage, that is supposed to increase up to unbelievably high values, to only cover the electricity production, is due to increase even more, to cover the TPES demand, and not only the electricity demand, of a country without combustion fuels.

However, its application requires to take into account the specific conditions necessary to determine both resources in accordance with the requirements of agents [64].…”

The article is devoted to the approaches that can be applied in the distribution of Arctic resources between the main reference countries of this region. The objective economic nature of the problems that arise in this region makes it possible to characterize them as a competition of claims for a limited and potentially dynamically changing resource. At a formal level, this problem has a general nature and it is typical for many areas of modern economy. At the same time, it is impossible to deny its specifics, which imposes significant restrictions on possible methods of solution. In recent years, problems in the sphere of interstate cooperation under conditions of limited resources have significantly increased. In such a situation, scientific and practical research in the field of mechanisms for regulating the relations between the parties (economic entities) becomes interesting. In analyzing the mechanisms of distribution of limited resources, one can use the theory of cooperative games, mathematical models of resource rationing, as well as works on the study of problems of equitable distribution (s.c. Fair Divisions). In the framework of such tasks, the range of applicants for limited resources can be limited to countries or regions directly adjacent. The process can be include of “external players” who have sufficient investment potential. The subsequent development and analysis of the problems of regulating intercountry interaction are associated with mathematical formalization. Such formalization presupposes a description of the situation of competitive interaction between countries in the form of a stochastic cooperative game. An analysis of possible concepts for the solution of this game will lead to meaningful conclusions about specific schemes (mechanisms) of rationing.
