Millions of sub‐daily sea‐level pressure observations taken between 1919 and 1960 over the British and Irish Isles were transcribed from paper records in the early 2000s but were not published and subsequently forgotten. A chance discussion led to the rediscovery of the transcribed data and 5.47 million observations from 160 locations are now made available, although the data have not been fully quality‐controlled. Much of the data are 3‐hourly, allowing for detailed examinations of synoptic weather variations for this region and time period, and will be invaluable for constraining future reanalyses. We illustrate the value of the data using a stormy period during October and November 1928 and discuss the remaining quality‐control issues. [ABSTRACT FROM AUTHOR]

Recovers and examines atmospheric pressure data recorded at the Madras Observatory, and at other climate stations in India, focusing on their quality and veracity. In general, the Madras monthly mean sea-level pressure (MSLP) record is shown to be robust over time, and thus a useful long-term measure of fluctuations in the El Niño southern oscillation (ENSO) phenomenon across the Indian Ocean basin and of the Indian summer monsoon.

Quantitative approaches to climate risk management such as mapping or impact modelling rely on past meteorological data with daily or sub‐daily resolution, a large fraction of which have not yet been digitized. Over the last decade or so, a number of projects have contributed to the rescue of some of these data. Here we provide a summary of a survey we have undertaken of several meteorological and climate data rescue projects, in order to identify the needs of climate data rescue services. To make these efforts more sustainable, additional integrated activities are needed. We argue that meteorological and climate data rescue must be seen as a continuous, coordinated long‐term effort. Technical developments (e.g. data assimilation), new scientific questions (e.g. process understanding of extreme events) and new social (e.g. risk assessment, health) or economic (e.g. new renewable energy sources, agriculture and forestry, tourism, infrastructure, etc.) services are highlighting the immense value of data previously neglected or never considered. This continuous effort is currently undertaken by projects of various sizes, structure, funding and staffing, as well as by dedicated programmes, ranging from those within many national weather services down to "grassroots" initiatives. These activities are often not sufficiently coordinated, staffed, or funded at an international level and will benefit considerably from climate data rescue services being established within the Copernicus Climate Change Service (C3S) (https://climate.copernicus.eu/).

The article discusses a meeting of the World Meteorological Organization Commission for Climatology on September 7-9, 2010 sponsored by Great Britain's Meteorological Office. It states the meeting discussed the creation of a comprehensive, traceable data bank of global surface temperature and facilitate high-quality, robust data product creation to meet the needs of 21st century climate research. It commented on the need for increased openness and transparency in research data policy.
