The MORE (MOLOCH Reanalysis over Italy) dataset provides high-resolution (~1.7 km) hourly weather data for Italy from 1990 to today, including precipitation, near-surface temperature, and 40 atmospheric variables. Validation shows it accurately reproduces local rainfall, temperature patterns, and extreme events, outperforming coarser datasets. MORE enables improved climate studies, flood risk assessment, and serves as a reference for climate services and advanced modeling applications.

Worldwide reconstructed historical aerosol load reveals that during the period of: 1900–1959: the atmosphere became cleaner in most European cities; 1960–1985: anthropogenic aerosols were responsible for the dimming phenomenon in Europe. AOD increased over Southeast Brazil and decreased noticeably over Japan while a small negative trend was found over Oceania; 1986–2015: generally, the atmosphere has become much cleaner everywhere after the reversal trend around 1980s mainly observed in Europe.

Understanding past climates requires data extending beyond modern instrumental records. This study shows that blue intensity (BI) measurements from European larch trees in the Southern Rhaetian Alps provide a stronger proxy for reconstructing past summer temperatures than traditional tree-ring-width data. BI processing enables regional-scale reconstructions and helps extend these reconstructions to the Mediterranean Basin and northern Europe, with excellent correlations to existing data.

This paper develops an observational integrated and homogenized global-terrestrial (except for Antarctica) SSRIH station. This is interpolated into a 5° × 5° SSRIH grid and reconstructed into a long-term (1955–2018) global land (except for Antarctica) 5° × 2.5° SSR anomaly dataset (SSRIH20CR) by an improved partial convolutional neural network deep-learning method. SSRIH20CR yields trends of −1.276 W m−2 per decade over the dimming period and 0.697 W m−2 per decade over the brightening period.

We have compared hourly precipitation totals measured by rain gauges installed and maintained by citizens against professional weather stations managed by the national weather services of Finland, Norway and Sweden. The manufacturer of the citizen rain gauges is Netatmo. Despite the heterogeneity of citizens' measurements, our results show that the two data sources are comparable with each other, though with some limitations. The results also show how to improve the accuracy of citizens' data.

Short summary
This study investigates hourly precipitation patterns and extremes across Italy using the MERIDA HRES reanalysis, a dataset that combines observations and weather models to reconstruct past atmospheric conditions. By analising 37 years of hourly data, the study identifies an increase in hourly extreme precipitation in Alpine areas during summer and southern coastal regions in autumn, providing insights into evolving precipitation patterns and supporting climate resilience planning.
