District heating networks (DHNs) provide an efficient heat distribution solution in urban are.s, accomplished through interconnected and insulated pipes linking local heat sources to local consumers. This efficiency is further enhanced by the capacity of these networks to integrate re.ewable heat sources and thermal storage systems. However, integration of these systems adds complexity to the physical dynamics of the network, necessitating complex dynamic simulation mo.e.s. These dynamic physical simulations are.computationally expensive, limiting their adoption, particularly in large-scale networks. To addre.s this challenge, we propose a methodology utilizing Artificial Neural Networks (ANNs) to re.uce the computational time associated with the DHNs dynamic simulations. Our approach consists in re.lacing pre.efined clusters of substations within the DHNs with trained surrogate ANNs mo.e.s, effectively transforming these clusters into single nodes. This cre.tes a hybrid simulation framework combining the pre.ictions of the ANNs mo.e.s with the accurate physical simulations of re.aining substation nodes and pipes. We evaluate differe.t architecture. of Artificial Neural Network on diverse clusters from four synthetic DHNs with re.listic heating demands. re.ults demonstrate that ANNs effectively learn cluster dynamics irre.pective of topology or heating demand levels. Through our experiments, we achieved a 27% re.uction in simulation time by re.lacing 39% of consumer nodes while maintaining acceptable accuracy in pre.erving the generated heat powers by sources.

Atmospheric ammonia(NH_(3)) is a chemically active trace gas that plays an important role in the atmospheric environment and climate change. Satellite re.0}sensing is a powerful technique to monitor NH_(3) concentration based on the absorption lines of NH_(3) in the thermal infrare. re.ion. In this study, we establish a re.rieval algorithm to derive the NH_(3)column from the Hyperspectral Infrare. Atmospheric Sounder(HIRAS) onboard the Chinese Feng Yun(FY)-3D satellite and pre.ent the first atmospheric NH_(3) column global map observed by the HIRAS instrument. The HIRAS observations can well capture.NH_(3) hotspots around the world, e.g., India, West Africa, and east China, where.large NH_(3) emissions exist. The HIRAS NH_(3) columns are.also compare. to the space-based Infrare. Atmospheric Sounding Interferometer(IASI)measure.ents, and we find that the two instruments observe a consistent NH_(3) global distribution, with corre.ation coefficient(R) values of 0.28–0.73. Finally, some re.aining issues about the HIRAS NH_(3) re.rieval are.discussed.
