A dense daily precipitation data base, extending from 1964 to 1993, has been created for the Mediterranean regions of Spain. It is composed complete and homogeneous series at 410 raingauge stations (347 in coastal fringe peninsular Spain, 63 Balearic Islands). The region offers an interesting scenario mesoclimatological studies on time spatial rainfall variability: geomorphologically, it characterized by important relief units complex distribution sea land masses, leading different exposures...
Abstract This paper presents trends in downward surface shortwave radiation (SSR) over Europe, which are based on the 56 longest series available from Global Energy Balance Archive that mainly concentrated central Europe. Special emphasis has been placed both ensuring temporal homogeneity and including most recent years data set. We have generated, for first time, composite time Europe covering period 1939–2012, studied by means of running trend analysis. The mean annual SSR shows an...

ABSTRACT We analyse recent trends and variability of observed near‐surface wind speed from 19 stations across Saudi Arabia (SA) for 1978–2013. The raw data set was subject to a robust homogenization protocol, the were then classified under three categories: (1) coast, (2) inland (3) mountain stations. results reveal statistically significant ( p < 0.05) reduction −0.058 m s −1 dec at annual scale SA, with decreases in winter (−0.100 ) spring (−0.066 also detected, being non‐significant...
Abstract Observations are the foundation for understanding climate system. Yet, currently available land meteorological data highly fractured into various global, regional, and national holdings different variables time scales, from a variety of sources, in mixture formats. Added to this, many still inaccessible analysis usage. To meet modern scientific societal demands as well emerging needs such provision services, it is essential that we improve management curation land-based holdings. We...
Abstract Assessing change in daily maximum wind speed and its likely causes is crucial for many applications such as power generation disaster risk governance. Multidecadal variability of observed near-surface (DMWS) from 778 stations over China analyzed 1975–2016. A robust homogenization protocol using the R package Climatol was applied to DMWS observations. The homogenized dataset displayed a significant ( p < 0.05) declining trend −0.038 m s −1 decade all annually, with decreases...
Abstract The homogenization of climate observational series is a needed process before undertaking confidently any study their internal variability, since changes in the observation methods or surroundings observatories, for instance, can introduce biases data same order magnitude than underlying variations and trends. Many have been proposed past to remove unwanted perturbations from climatic series, some them implemented software packages freely available on Internet. Spanish project...
Daily Peak Wind Gust (DPWG) time series are important for the evaluation of wind‐related hazard risks to different socioeconomic and environmental sectors. Yet, wind analyses can be impacted by several artefacts, both temporally spatially, which may introduce inhomogeneities that mislead study their decadal variability trends. The aim this is present a strategy in homogenization challenging climate extreme such as DPWG using 548 across Australia 1941–2016. This automatic implemented recently...
Abstract Time series homogenization for 299 of the available precipitation records island Ireland (IENet) was performed. Four modern relative methods, that is, HOMER, ACMANT, CLIMATOL and AHOPS were applied to this network station where contiguous intact monthly range from 30 70 years within base period 1941–2010. Break detection results are compared between coincidences with documentary information (metadata) analysed. The lowest (highest) number breaks detected HOMER (ACMANT). Large...
Abstract Reliable secular time series of essential climatic variables are a fundamental element for the assessment vulnerability, impact and adaptation to climate change. Here, we implement readily portable procedure building an upgradable long‐term homogeneous dataset using monthly daily observations temperature precipitation over given area interest, exemplified here with Abruzzo, region in Central Italy characterized by complex orography. We process according preliminary ranking stations...
Abstract This study analyses for the first time break in stilling detected by previous research around 2010, with focus Sweden using homogenized near‐surface mean and gust wind speed observations 1997–2019. During recent past two decades, both magnitude frequency (exceeding 90th percentile) underwent nonlinear changes, driven dominant winter variability. In particular, consistent studies, significant ( p < .05) ceased 2003, followed no clear trend afterwards. The stilling‐reversal is...
High quality and long-term precipitation data are required to study the variability trends of rainfall impact climate change. In developing countries like Morocco, collected from various weather stations faces numerous obstacles. This paper presents methods for collecting, correcting, reconstructing, homogenizing series Morocco’s Fez-Meknes region 1961 2019. Data national specialized agencies based on 83 rain gauge was processed through an algorithm specially designed homogenization climatic...
Near-surface wind speed exerts profound impacts on many environmental issues, while the long-term (≥60 years) trend and multidecadal variability in its underlying causes global high-elevation mountainous areas (e.g., Tibetan Plateau) remain largely unknown. Here, by examining homogenized data from 104 meteorological stations over Plateau for 1961‒2020 ERA5 reanalysis datasets, we investigated near-surface revealed role played westerly Asian monsoon. The results show that annual displays a...

ABSTRACT In this work, we present results of the development an observation‐based gridded climate dataset (ClimUAd), which covers territory Ukraine for period 1946–2020. The spatial resolution developed data is 0.1° × (approximately 10 km in both longitude and latitude directions), with a 1‐day time step. Four essential variables are included dataset, namely daily sums atmospheric precipitation minimum, mean, maximum air temperature. created product based on complete collection station...

These differences are generated from Global Positioning System (GPS) measurements at sites worldwide, and numerical weather prediction reanalysis (ERA‐Interim) output, which serves as reference here. The includes homogeneous inhomogeneous sections with added nonclimatic shifts (breaks) in latter. Three variants...
Abstract The aim of time series homogenization is to remove nonclimatic effects, such as changes in station location, instrumentation, observation practices, and so on, from observed data. Statistical usually reduces the effects but does not them completely. In Spanish “MULTITEST” project, efficiencies automatic methods were tested on large benchmark datasets a wide range statistical properties. this study, test results for nine versions, based five methods—the adapted Caussinus-Mestre...
