Currently a research member of IDL-LA and also technical coordinator of the oldest Portuguese observational meteorological station in Lisbon at IDL-Politécnica Lisbon Geophysical Institute). Working in Portuguese historical data analysis and digitisation Most recent work (since 2006) includes: Co-coordination of project SIGN (2006-2008), set to recover selective sub-daily historical meteorological observations of the 3 Portuguese Geophysical Institutes containing the longest data series in Portugal (Lisbon, Porto and Coimbra). Principal Investigator of the FP7 ERA-CLIM project (Portuguese partner) (2011-2013) - Towards building a reanalysis by ECMWF for the 20th century - ERA-20C. Principal Investigator of the FP7 ERA-CLIM2 project (Portuguese partner) (2014-2016) - Second phase of ERA-CLIM. In the ERA-CLIM projects (, data from Portugal and former Colonies (Angola, Mozambique, Guiné-Bissau, Cabo Verde, São Tomé e Principe, Macau, Goa and Timor) is being digitised, quality controlled, homogenised and supplied to the first versions of ERA-20C. Active member of ACRE (Atmospheric Reconstructions over the Earth - Data supplier of surface pressure to the 20CR reanalysis (NOAA/CIRES).
