1974 - He set up the Remote Sensing Unit at the ISS which he directed until 2003; he organised and managed 79 Projects over the years, flying over 600 hours in a number of locations in Italy on helicopters and Goodyear's Europa 2 dirigible, 
2003 - He resigned from the ISS and set up a Company, Catena & Thermography, to devote himself to developing Thermography applied to tree assessment. 

He was a member of the following organisations and committees as Thermography Expert: 
1976 - NATO's Marine Science Panel on the standardisation of the analyses needed in case of polluting spillages at sea, Venice, 
1976 to 1999 - He conducted thermal investigations for the Presidency of the Italian Republic, for some Italian Ministries and Regions and at the order of some magistrates, 
1977 to 1980 - Ad hoc Group for the selection of actions and methods to control coastal water quality in the Mediterranean, set up at the Italian Institute of Health, in the framework of the WHO-UNEP Pilot Project on the control of the quality of Mediterranean coastal waters (Med VII), 
1978 - Monitoring of recreational coastal water quality and shellfish culture areas within the framework of WHO/UNEP pilot project Med VII, 
1983 to 1985 - Commission appointed by the Italian President's Office for the protection of the trees of the Presidential estate of San Rossore (Pisa), 
1985 to 1989 - Commission appointed by the Italian President's Office to draft the working plan for the trees of the Presidential Estate in Castelporziano (Rome); on this occasion, he used thermography for the census of the wildlife from the ground and onboard helicopters,
1997 to 1999 - Concerted Action on Algal Bloom Detection, Monitoring and Prediction (ABDMAP), European Commission Framework IV, Centre for Earth Observation: a European project for the study of the problem of toxic algal blooms in European seas. 

RESEARCH ACTIVITY 

He took an interest in the use of Remote Sensing and Thermography in various sectors over the years, to later devote himself to Thermography-aided tree stability assessment. In over thirty years of work, he has gathered over 40,000 pictures and thermograms, that were taken both from the ground and in flight. 
1973 - Together with his assistant Lanfranco Palla, he started using Remote Sensing techniques, in particular Thermography, which had only just started to be used in the civil sector, to study environmental pollution, 

1974 - 2003 He set up the Remote Sensing Unit at the ISS which he managed until he resigned from the ISS. The Unit employed Thermography and Aerial Photography to spot water effluents, algal blooms, underground archaeological finds, scattered landfills, to take censuses of ungulates in the wild, and as a support to chemical and microbiological analyses to assess bathing waters, etc. In this sector, this has helped him develop a system that combines aerial pictures of coast areas with thermal images of the coast and identifies polluting sources and helps fight the pollution of bathing waters. Dr Catena was convinced that trees were an actual pollution indicator, therefore he started studying the possibility of using special IR films to detect pollution-caused diseases in trees. This method was first applied in 1983 at the Presidential estate of San Rossore (Pisa), in the context of studies on the deterioration of the pinewood. Animal census was one of the issues of interest for Dr Catena, in fact he applied Thermography to the study of ungulates, wild boars and deer, in case of thick wood or forest, where these animals may pose a serious problem to manage the territory. In case of thick forests, traditional animal censuses may take a long time, are expensive and require a lot of personnel. Dr Catena thought of flying an IR camera on the areas of interest to visualise and count animals as their body temperature was higher than the surrounding environment and made them visible. He has demonstrated the applicability of the method also in the summer, with no snow, unlike what was stated by articles published in the United States. He also suggested using this technique to study the behaviour of the bat population,
 
1984 - He introduced Thermography in tree assessment, with his assistant Lanfranco Palla, thus creating a truly non invasive system that can detect decay and cavities in tree trunks and branches from a distance and from the ground, while also visualizing residual healthy tissue and highlighting decay and cavities in the root system, unlike any other apparatus, and generating Thermography-aided tree stability assessment - Treethermography® - TTH. As a matter of fact Dr Catena soon realised that the system showed decay and cavities because it could assess tree tissue vitality. That is why, the system "sees" root decay without unearthing roots, assesses vitality in veteran trees and shows rejuvenating tissue before the process is visible from the outside. This intuition was confirmed when trees that had not been considered as dangerous and left standing were re-assessed. Dr Catena developed a case study of a few thousand examined trees - conifers, broadleaved and palm trees: in over 300 cases, he could confirm the diagnosis with invasive apparatuses, by introducing probes in existing holes or also after felling the trees that were deemed dangerous, 

2003 - to date, After he resigned from the ISS, he set up his Company, Catena&Thermography, with his daughter, Alessandra, who graduated in Forestry and Environmental Sciences from Tuscia University, Viterbo, with the aim to disseminate the use of Treethermography® - TTH. To this end, they went to the UK, Netherlands, and Germany, on a number of occasions, in order to conduct measurements, introduce the method and deliver Presentations in congresses or for public bodies and/or specialised users. After closing the company, he has continued with research studies - especially with the re-assessment of the trees examined over 20 years ago, moreover, he writes articles and teaches the technique to arboriculturists and thermal imaging experts who want to use it. The possibility that he has had to re-analyse the same trees over time, even after many years, gave him a unique experience and competence. He is author and co-author of over 100 articles (over 50 on Treethermography® - TTH) published in national and international journals; he delivered Presentations with his daughter Alessandra at Italian and International Congresses and Workshops. Until he resigned he has been a member of the SIA (ISA - Italian Chapter) and the Remote Sensing Society (UK), now Remote Sensing and Photogrammetric Society - RSPSoc (UK) for 26 years. He is member of the Arboricultural Association (UK).
