O estudo foi realizado no âmbito da Geografia Física, numa perspectiva interventiva e de aplicação prática, no domínio da Climatologia Aplicada, com o objectivo de contribuir para um melhor planeamento e ordenamento do território, no que ao espaço florestal diz respeito. Foram escolhidos dois anos com “verões” de características opostas. O ano de 2005, por ser aquele que detém o maior número de ocorrências, desde que há registos e, além disso, ocupa o segundo lugar, em termos de área ardida. Por sua vez, considerou-se o de 2008, por ter sido aquele que, nos últimos 20 anos, registou menos ocorrências e, também, a área ardida inferior. Analisaram-se 244 cartas sinópticas, correspondentes aos 122 dias dos meses de cada um doas anos, no que respeita aos campos de pressão à superfície (nmm) e em altitude (500 hPa), examinando a frequência do tipo de tempo, identificando a ocorrência dos tipos de anticiclones, confrontando com o tipo de circulação existente, observando-se a frequência da depressão térmica ibérica estival, registando a frequência da ruptura da “circulação contornante” da Península Ibérica e o rumo do vento. Por último, relacionaram-se as condições sinópticas registadas com a frequência das ocorrências, com as áreas queimadas pelos incêndios florestais, e, ainda, com a ocorrência de grandes incêndios, com área ardida igual ou superior a 100 ha, concluindo-se que existe uma forte dependência entre a ocorrência/progressão dos incêndios florestais e as condições de tempo que lhes são mais favoráveis, do mesmo modo que se reduz drasticamente, quando elas são desfavoráveis.

The research expound that exposure to heat and cold waves resulted in a rise in the overall mortality rate (namely in elderly population with ≥65 years old), albeit dependent on the vulnerability of exposed populations. During heat waves the mortality rate increased on the 3rd day after the start of the event and continued during the subsequent days. Greater mortality rate was registered in women and the elderly, particularly those with circulatory and respiratory diseases. In the case of cold waves, it was ascertained that an increase of mortality rate occurred as of the 7th day after the start of the event and continued in the subsequent days, having a greater incidence on the elderly and women, and those with circulatory and ischemic heart diseases. Social vulnerability to heat and cold waves is greater in parishes with higher demographic density and percentages of elderly people, especially in the historic centre and in rural areas.

In this scope, the heat wave that occurred in Europe in the summer 2003 has been deeply studied, both in its causes and in its consequences for public health. This paper presents a first analysis about the impact of heat on mortality levels of the population living in Coimbra municipality, focusing on daily temperature values (average, minimum and maximum) registered during the summer 2003 and the daily number of deaths by specific causes occurred in the same period. The aim is to verify the existence, for each sex, of statistical associations between temperature values and cause-specific mortality. The results show a varying relationship between temperature and mortality, in accordance with cause of death and sex. Identifying the causes of death that are more sensitive to temperature is assumed as an initial step of a wider study, in which we seek to evaluate the relationship between climate and mortality, using factors of vulnerability (sensitivity and exposure) related to diverse socioeconomic, demographic and urban conditions.

The new isothermal maps of return values of maximum and minimum air temperatures at mean sea level for 50, 100 and 120-year return periods based on the generalised extreme value distribution will be crucial to inform the design of buildings and bridges. The warming of the maximum and minimum air temperatures due to climate change has increased the intensity of the highest maximum air temperature while decreasing the intensity of the lowest extreme minimum air temperature of the new isothermal maps compared to previously published maps for a 50-year return period. Specifically, the new extreme isotherms are 32 • C for the maximum air temperature and −14 • C for the minimum air temperature, whereas the processor maps presented 30 and −16 • C, respectively. The geographical distribution of the isotherms for the 120-year return period range from 28 to 34 • C for the maximum air temperature and from −6 to −18 • C for the minimum air temperature. For the first time, isothermal maps of return values of the lowest 10 cm soil temperature for 50, 100 and 120year return periods based on the generalised extreme value distribution have been produced for Ireland. The results presented here will be paramount to supporting the design of building structures. The values of the 120year return period range from 0 to −2 • C. The produced maps represent the worst-case scenario in the current context of climate warming. The new maps of return values of snow loading at 100 m above mean sea level for 50, 100 and 120-year return periods based on the generalised Pareto distribution will be indispensable to support the design of buildings and civil engineering works such as roof patterns or bridges. The values of the 50-year return period map present four classes spread NorthEast to SouthWest: < 0.3, 0.3-0.4, 0.4-0.5 and 0.5-0.6 kN m −2 , which is more accurate than the previously published map. It is expected that the comprehensive explanation of the methods and the rationale for the new maps presented here as being more accurate than the preceding maps will assist regulators in adopting these new maps in their own jurisdictions. Furthermore, these new maps will be of interest to a diversity of sectors, planners and policymakers to make long, lasting and climate-based sensitive decisions.

However, quality control and homogenisation procedures are required to minimise errors and inhomogeneities in climate series before the commencement of climate data analysis. A semi-automatic quality control procedure consisting of climate consistency, internal consistency, day-to-day step-change, and persistency tests was applied for 12 long-term series registered in Ireland from 1831–1968, Armagh Observatory (Northern Ireland) from 1844–2018, and for 21 short-term series dating to the mid-19th century. There were 976,786 observations quality-controlled, and 27,854 (2.9%) values flagged. Of the flagged records, 98.5% (n = 27,446) were validated, 1.4% (n = 380) corrected and 0.1% (n = 28) deleted. The historical long-term quality-controlled series were merged with the modern series quality-controlled by Met Éireann and homogenised using the software MASHv3.03 in combination with station metadata for 1885–2018. The series presented better homogenisation outcomes when homogenised as part of smaller regional networks rather than as a national network. The homogenisation of daily, monthly, seasonal, and annual series improved for all stations, and the homogenised records showed stronger correlations with the Central England long-term temperature series.

This research provides the first assessment in Ireland of the frequency, duration, intensity and geographical distribution of the daily extreme air temperature indices recommended by the ETCCDI (Expert Team on Climate Change Detection and Indices) and based on long-term rescued, quality-controlled and homogenised data. Prior analysis of air temperature indices in Ireland had focused on the period since the second half of the 20th century, where digital data were readily available. Earlier estimations of long-term air temperature trends in Ireland focused on non-homogenised data from a small network of stations. For this research, 11 long-term (1885-2018) maximum and minimum air temperature series were analysed to assess seasonal and annual trends and construct extreme air temperature indices in Ireland. The non-parametric Mann-Kendall test was employed to test the statistical significance of the maximum and minimum air temperatures and indices trends (p < 0.05). Significant increasing trends were assessed in the seasonal and annual maximum and minimum air temperature series in Ireland, with greater increases in the spring and autumn seasons. Significant increasing trends were determined in the warm days (+6.8 days), warm nights (+7.5 nights), warm spell duration index (+3.9 days), growing season length (+22 days), coldest night (+2.7 • C) and coldest day (+1.5 • C) in the period 1885-2018 in Ireland. In the same period, significant decreasing trends were identified in the cold days (− 9.3 days), cold nights (− 7 nights), frost days (− 13.7 days), cold spell duration index (− 6.9 days) and diurnal air temperature range (− 0.1 • C) in Ireland. The results follow global patterns presented in the Six Assessment Report of the Intergovernmental Panel on Climate Change. The findings of this research will be crucial to assist stakeholders and policymakers in defining climate action, adaptation and mitigation plans in response to shifting trends in air temperature extremes.

Long-term series are fundamental for the assessment of frequency, duration, intensity and geographical distribution of past extreme air temperature events at local and regional scales in Ireland. Raw daily observations from 12 long-term and 21 short-term maximum and minimum air temperature series in Ireland, extending from 1831 to 1968, were rescued from multiple archives. Detailed station metadata on instrumentation, site location, observation practices and observer's notes are included in the dataset. Over 970,000 daily maximum and minimum air temperature observations were transcribed from handwritten meteorological registers, publications, newspapers and the Daily Weather Report. The data rescue strategies, sources for data and metadata rescue, and methodologies for double keying are discussed. The Ireland Long-term Maximum and Minimum Air Temperature dataset (ILMMT) format for daily air temperature and metadata and organization is reviewed. The ILMMT dataset comprises raw observations and detailed station metadata, so data users can apply their selected quality control and homogenization approaches.

The inventory comprises references on the location of registers, metadata, data holders and data sources. The majority of registers remain as handwritten records or publications kept in various archives across Ireland and abroad or as online resources such as scanned newspapers. This inventory will aid future climate data rescue projects in Ireland.

Student–scientist collaborations between secondary schools, universities, national meteorological services, and archives have the potential to be applied elsewhere and contribute to a fast, accurate and low-cost climate data rescue process. Service-learning partnerships in climate data rescue projects are crucial to communicate climate science and to enhance climate data literacy outside the school curriculum. Secondary school students–scientists partnerships are an important new avenue for climate data rescue projects.
