C3S Data Rescue Service
Southern Hemisphere Data Rescue Foci

Linked to ACRE Argentina - led by Dr. Pablo Canziani, Investigador Principal CONICET, Unidad de Investigación y Desarrollo de las Ingenierías, Facultad Regional Buenos Aires, Universidad Tecnológica Nacional (UTN), Buenos Aires, Argentina. The UTN will coordinate activities with other national organisations such as Armada de la República Argentina, Prefectura Naval Argentina, Servicio Meteorológico Nacional, MinCyT and national and provincial archives. Contacts with private shipping companies or the institutes of no longer existing companies as well as estancias re historical ship log books and weather records.   
•    Logbooks from Argentine ships and ‘stationary’ ships in port
•    Observations from lighthouses
•    Digitisation of Buenos Aires observations from the 1820s onwards
•    Gaps in DWD old German colonial observations between 1903 and 1930
•    Observations from old railway companies
•    Argentine Daily Weather Reports (DWRs) from 1902-1980, which are held by the Met Office Archives in the UK.  These DWRs not only contain daily observations of many ECVs for Argentina (e.g. pressure, temperature, winds, relative humidity and precipitation) but also contain similar records for neighbouring countries, and will be scanned and digitised in order to improve historical weather data coverage in the wider South American sphere.  In ISPDv4, the most currently available version of the ISPD, there are no data for Argentina prior to 1939 (http://www1.ncdc.noaa.gov/pub/data/ispd/add-station/v4.0/).   

•    2018-19 C3S Data Rescue Service Capacity Building Workshop

Linked to ACRE South Africa - led by Prof. Stefan Grab, School of Geography, Archaeology and Environmental Studies, University of the Witwatersrand (UWits), Johannesburg, South Africa. With this regional focus, we are looking to establish a southern African data rescue component with the South African Weather Service (SAWS) within the Weather and Climate Science to Services Partnership project for South Africa (WCSSP South Africa). The longest and most promising continuous single station record in South Africa is that from the Royal Astronomical Observatory in Cape Town (today known as the South African Astronomical Observatory – SAAO). Original Meteorological records have been found and photographed by UWits scholars at the SAAO and Cambridge University Archives. The record includes the ECVs of daily rainfall, temperature, barometric pressure and wind. Currently two PhD students are working with this historic daily record, which begins in 1834 and continues to this day. This record requires calibration and quality checking; hence additional records from the former Cape Colony would be invaluable in this process.
•    Photograph and digitise Gordon’s meteorological Journal of daily barometric and some temperature readings from 22 Sept 1789 to 21 June 1792 for Cape Town, Meteorological Diaries kept at the Cape Town Port Office (Harbour Masters records), archived in the Cape Town Archives (1829-1893), and the Meteorological Diaries for the Cape Colony (1821 onwards).
•    Recovery and digitisation of daily to sub-daily data for the South African stations shown in light blue, covering the period 1875-1909 held at the SAWS photographed and digitized (see in light blue markers below).  It should be noted that the only stations that have had their daily to sub-daily data digitised by ACRE and partners (see in black stars below), and that have been incorporated into ISPDv4 and used in reanalyses, are Cape Town, Kimberley and Durban. Digitisation by local students will provide them with both vital experience and provide vital income.
•    Recovery, imaging and digitisation of historical weather observations taken by ‘stationary’ ships in ports around southern Africa and nearby islands (see below)
•    Support digitisation for The Mauritius Project (ACRE & Indian Data Rescue initiative [INDARE])

Linked to ACRE Antarctica (http://www.met-acre.org/data-projects-and-regional-chapters/acre-antarctica) – is led by Dr. Drew Lorrey, National Institute of Water and Atmospheric Research (NIWA), Auckland, New Zealand, with initial funding under the New Zealand Deep South National Science Challenge (http://www.deepsouthchallenge.co.nz/) as part of the program on ‘Assessing and validating the New Zealand Earth System Model (NZESM) using modern and historic observations’. In ACRE Antarctica, critical past weather observations are being rescued across the Southern Ocean sector shown below, as part of a Southern Ocean Sea-Ice, Meteorology and Oceanography Present Data Recovery effort, in conjunction with Clive Wilkinson and the Met Office, for the purpose of extending Southern Hemisphere coverage within global reanalyses as far back as possible into the 1800s. Sources as diverse as the British Antarctic Survey, the UK National Archives, UK National Meteorological Library & Archive, Scott Polar Research Institute at Cambridge University, the Whaling Museum and Vestfold Archives at Sandefjord, in Norway, the Åland Maritime Museum at Mariehamn in Finland, the Museo Marítimo Nacional at Valparaíso in Chile, and the marine records of Deutscher Wetterdienst (DWD) have been examined.   Primary work consists of identifying data resources, digital scanning, data digitisation, quality control, and archiving of the observations. Rescued data are being archived and made publicly available through the ISPD and NIWA's database.   
The C3S Data Rescue Service will support ACRE Antarctica through:
•    a citizen science project which will be developed to digitise the historical marine data rescue recovered and imaged across the Southern Ocean sector of ACRE Antarctica (see below). Priorities are:
o    Transport & immigration vessels: e.g. British merchant ships from Australia and New Zealand to South America; annual/ biannual cruises by the Armada Argentina to Antarctica since 1903
o    Whaling & sealing ships
o    Exploration vessels
•    the variables/observations focused on (which align to ECVs) will be surface pressure, air temperature, sea surface temperature and sea ice, with the main aim of improving the reanalysis and length of observations in order to reconstruct better high mid-latitude climate modes of the Southern Hemisphere.

•    10th ACRE Workshop & C3S Data Rescue Services Capacity Building Workshop, NIWA, Auckland, NZ: 4th-8th December 2017

The above three data rescue activities will receive the following support from C3S Data Rescue Service WP3.
Météo-France & NIWA (ACRE Pacific) will provide additional inventories of sources, inventories of the images and list of data to be rescued in the Pacific (SW Pacific, New Caledonia, Wallis et Futuna, Vanuatu and Polynesia) and Météo-France & INDARE/UWits (ACRE South Africa) African region (southern Africa, Madagascar, Reunion and the Comoros). JLU will provide data digitisation and QC support to any of the Argentine and South African data rescue efforts. CIRES is the main partner with experience in generating historical reanalysis fields from rescued meteorological data, and their 20CR uncertainty field provides important input to guiding the selection of high-priority data rescue targets for each of the three regions above.
