The project team, together with the help of the students, is working on the measurement of the cooling effect of urban greenery. 
Temperature measurements done within this project are both stationary ( at one location) and mobile (a trajectory).

• The stationary measuring instruments record the temperature and humidity every hour

So far, Kestrel Drops (the so called "eggs") are located at 10 different locations since the end of June 2019. The temperature and relative humidity data is being downloaded regularly for further analysis. Other parameters such as the dew point temperature and heat stress, can be calculated based on that information. The day when the drops are placed and the time span is certainly being kept up to date, because the batteries will have to be replaced at some point if necessary.

• De mobile measurement instruments record the Heat stress 

These Kestrel Link heat stress trackers can record different variables while walking with them. We have focused on the temperature, wind speed and humidity of the environment as we move further away from a piece of greenery. With this information the heat stress can be determined and see in which way forest fragments or trees can cool the environment.

In transects per location are being walked at a low pace so that the data can be recorded per second. The locations with transects are being searched with the GeoSurvey software on a tablet. While walking, the walking speed can also be seen via this software.

We have carried out mobile measurements in both the rainy season and the dry season and thanks to individuals and organizations, such as the Father Anton Donicie group of Boy Scouts and the Nola Hatterman Institute, we can already collect data continuously at 10 locations. In the next phase of the project, more stationary measurement points will be added by asking citizens to 'adopt an egg'. Furthermore, the analyzed data will also be visible on a map placed on the website.

Paramaribo Green, (we have to) do it together!
