The first specific objective (SO1) of CLARITY was to deepen the understanding of fluctuations inherent in climate data.
In the course of CLARITY realization, and in order to accomplish realization of this specific objective, we focused our analysis on: a) two prominent sources of global temperature monthly data, the UK Meteorological Office HadCRUT4 and the NASA Goddard Institute for Space Studies (GISS) LOTI gridded monthly historical records, b) land stations absolute temperature monthly records, c) historical daily flow records of the river Danube in the vicinity of the two dams – Iron Gates or Djerdap I and II, and d) ambient UVR in schools and public places in the city of Venice and its surrounding (islands and the mainland) and personal exposure to solar UVR collected by the groups of tourists visiting the city of Venice during the summer of 2017.
We used the 2nd order DFA analysis in combination with the wavelet transform power spectral (WTS) analysis to investigate our data. We applied both monofractal and multifractal formalisms to study our data.
Figure 1. attached to this report gives an example the results of the scaling analysis of the global temperature data.

This part of CLARITY brought together research groups from South Africa, New Zealand, Serbia, and Italy.
The second specific objective (SO2) of CLARITY was to incorporate information on data dynamics into climate modelling strategies developed by DAIS's research group of CLARITY realization supervisor.
In the summer of 2017 the CLARITY DAIS's group finalized their modelling approach based on an unified statistical Bayesian framework. They used it in combination with the coupled ROMS-PISCES global ocean biogeochemical model.
As a part of CLARITY realization, two research tasks were realized, connected to this modelling efforts: 1) analysis of modelled Tropical Atlantic fisheries data, and 2) production of recommendations, based on the results of scaling analysis, for the changes in ROMS-PISCES simulation. As an output a new solution was devised for the possible different modelling approach.
The third specific objective (SO3) of CLARITY was to apply the analysis and modeling techniques developed under the SO1 and SO2 to obtain more accurate models of the microclimatology of the city of Venice.
In the course of CLARITY realization, seasonal monitoring of ambient UVR was performed in or in the vicinity of 10 primary and secondary schools and one kindergarten in Venice and its surroundings, as well as in the main town hospital in Venice, in the two UNIVE buildings in the city of Venice and in its Science Campus in Mestre. Additional recordings were made during the summer 2017 in the areas of Venice art/architecture Biennale in Giardini area, and of the Film Festival in the island of Lido, in the vicinity of three Venice’s public museums, and on Venice’s Lido beaches. All these measurement provided for the large amounts of data (in the scale of 10^6 data points) that are shared publicly at CLARITY web-site.
Figures 2. and 3. show UVR measuring devices, placed on the main building of UNIVE over the Venice's Grand Canal.
Figures 4. and 5. attached to this report show Twitter announcement of public presentation of CLARITY pUVR results at the Museum of Natural History in Venice, and a graph of Venice’s UV Index for that year.
