Abstract The Twentieth Century Reanalysis (20CR) project is an international effort to produce a comprehensive global atmospheric circulation dataset spanning the twentieth century, assimilating only surface pressure reports and using observed monthly sea‐surface temperature sea‐ice distributions as boundary conditions. It chiefly motivated by need provide observational with quantified uncertainties for validations of climate model simulations century on all time‐scales, emphasis statistics...
Abstract We present a dataset of daily resolution climatic time series that has been compiled for the European Climate Assessment (ECA). As December 2001, this ECA comprises 199 minimum, maximum and/or mean temperature and 195 precipitation amount observed at meteorological stations in Europe Middle East. Almost all cover standard normal period 1961–90, about 50% extends back to least 1925. Part (90%) is made available climate research on CDROM through Internet (at...
Abstract This paper describes the HISTALP database, consisting of monthly homogenised records temperature, pressure, precipitation, sunshine and cloudiness for ‘Greater Alpine Region’ (GAR, 4–19°E, 43–49°N, 0–3500m asl). The longest temperature air pressure series extend back to 1760, precipitation 1800, 1840s 1880s. A systematic QC procedure has been applied a high number inhomogeneities (more than 2500) outliers 5000) have detected removed. 557 are kept in different data modes: original...
Historical reanalyses that span more than a century are needed for wide range of studies, from understanding large‐scale climate trends to diagnosing the impacts individual historical extreme weather events. The Twentieth Century Reanalysis (20CR) Project is an effort fill this need. It supported by National Oceanic and Atmospheric Administration (NOAA), Cooperative Institute Research in Environmental Sciences (CIRES), U.S. Department Energy (DOE), facilitated collaboration with...
Abstract The Italian monthly temperature (mean, maximum and minimum) precipitation secular data set was updated completely revised. Station density metadata availability were greatly improved the series subjected to a detailed quality control homogenisation procedure. is described in detail. bias affecting original quantified by studying temporal evolution of mean adjustments applied examined light stations history. results stress importance climate change studies. final clustered into...
Abstract This paper investigates temperature variability in the Alps and their surroundings based on 97 instrumental series of monthly mean temperatures. A discussion initial homogenizing procedure illustrates its advantages risks. comparison homogenized with original clearly shows necessity to homogenize. Each had breaks (an average five per series) all was systematically biased by non‐climatic noise. noise has subdued long‐term amplitude evolution region 0.5 K. The relatively high spatial...
We analyze century‐long daily temperature and precipitation records for stations in Europe west of 60°E. A set climatic indices derived from the series, mainly focusing on extremes, is defined. Linear trends these are assessed over period 1901–2000. Average trends, 75 mostly representing 20°E, show a warming all indices. Winter has, average, warmed more (∼1.0°C/100 yr) than summer (∼0.8°C), both maximum (TX) minimum (TN) temperatures. Overall, TX winter was stronger warm tail cold (1.6 1.5°C...
Abstract Productivity of old‐growth beech forests in the Mediterranean Basin was measured by average stem basal area increment (BAI) dominant trees at two mountain sites Italian Apennines. Both could be ascribed to stage, but they differed markedly with regard elevation (1000 vs. 1725 m a.s.l.), soil parent material (volcanic calcareous), mean tree age (less than 200 years 300 years), and stand structure (secondary primary forest). Drought quantified self‐calibrated Palmer Moisture Anomaly...
The International Surface Pressure Databank ( ISPD ) is the world's largest collection of global surface and sea‐level pressure observations. It was developed by extracting observations from established international archives, through cooperation with data recovery facilitated Atmospheric Circulation Reconstructions over Earth ACRE initiative, directly contributing universities, organizations, countries. dataset period currently 1768–2012 consists three components: land stations, marine...
Abstract Instrumental meteorological measurements from periods prior to the start of national weather services are designated “early instrumental data.” They have played an important role in climate research as they allow daily decadal variability and changes temperature, pressure, precipitation, including extremes, be addressed. Early data can also help place twenty-first century climatic into a historical context such defining preindustrial its variability. Until recently, focus was on...
Abstract A new daily precipitation dataset, for the period 1920–1998, comprising seven stations located in northeastern Italy is presented. Seasonal and annual number of rainy days have been analysed a study aimed at investigating intensity extreme events has performed. Precipitation through studying both mean amount per wet day dividing into heavy non‐heavy classes. In addition, return calculated 30‐year running windows its variations examined. The results show negative trend associated...
The paper describes the development of a dataset 192 monthly precipitation series covering greater alpine region (GAR, 4–18°E by 43–49°N). A few time extend back to 1800. description is provided sometimes laborious processes that were involved in this work: from locating original sources data homogenizing records and eliminating as many outliers possible. Locating required exhaustive searches archives currently held yearbooks other states, countries smaller regional authorities existed at...
Abstract An extensive analysis of the HISTALP database is presented with aim giving a comprehensive picture secular climate variability and change in Greater Alpine Region (GAR, 4–19 E, 43–49 N). The encompasses 242 sites concerns temperature, pressure, precipitation, cloudiness, sunshine duration, vapour pressure relative humidity. analyses are based on four regional mean records representing different GAR low‐level areas an additional record high‐level locations. first goal paper to give...
Abstract An analysis of 67 sites daily precipitation records over the 1951–1996 period for Italy is presented. Seasonal and yearly total (TP), number wet days (WDs) intensity (PI) are investigated, trends both single station records, some different area average series studied. PI analysed by attributing to ten class‐intervals, removing influence variations in WDs yield changes underlying shape WD amount distribution. The results show that trend year significantly negative throughout Italy,...
Abstract Aim To identify the dominant spatial patterns of Fagus sylvatica radial growth in Eastern Alps, and to understand their relationships climate variation bioclimatic gradients. Location Fourteen beech stands growing between 200 1500 m a.s.l. Italy, Slovenia Austria. Methods At each site, trees were sampled using increment borers or by taking discs from felled trees. Cores processed measuring crossdating ring width. Ring width series standardized, averaged, prewhitened obtain site...
A new data set of 45 daily precipitation series, covering quite uniformly Italian territory for the period 1880–2002, was recovered. The series have been homogenized on basis, completed by means statistical methods and grouped into five regions a Principal Component Analysis. Seasonal yearly total precipitation, number wet days, intensity were analyzed each station record averaged regional synthetic description results. Proportion frequency rainfall amounts, belonging to six class‐intervals,...
ABSTRACT High‐resolution monthly precipitation climatologies for Italy are presented. They based on 1961–1990 normals obtained from a quality‐controlled dataset of 6134 stations covering the Italian territory and part Northern neighbouring regions. The computed by means two interpolation methods modelling precipitation‐elevation relationship at local level, more precisely weighted linear regression (LWLR) kriging (RK) performed. For both methods, optimisations also applied in order to...
ABSTRACT High‐resolution monthly temperature climatologies for Italy are presented. They based on a dense and quality‐controlled observational dataset which includes 1484 stations three distinct approaches: multi‐linear regression with local improvements ( MLRLI ), an enhanced version of the model recently used Greater Alpine Region, kriging RK widely in literature and, lastly, weighted linear (LWLR) versus elevation, may be considered more suitable complex orography characterizing Italian...
