description Background tracks of Mosquito Alert participants in 0.05 and 0.025 degree longitude/latitude sampling cells with minimal processing. The temporal coverage for 0.025 starts from 2018, while for 0.05 degree resolution starts from 2014. This dataset contains data only on Android participants until 2020, when background tracking was implemented in the iOS app as well.

measurementTechnique
  • Sampling. Anonymous citizen scientists send reports of possible observations of mosquitoes, their breeding sites and bites using the open source and free smartphone app Mosquito Alert. To send an observation, participants need to answer a small questionnaire (taxonomic questions in the case of mosquitoes or some descriptors in the case of breeding sites), indicate the location (current participant location or selecting it on a map), add a picture (optional) and notes or comments (optional). The app and project website offers information to help identify the target species and take good pictures that allow a proper post validation from entomologists (see more information onQuality Control section). Participants can edit or remove the observation at any time (only if the participant still maintains the Mosquito Alert app in their phone). The last version of each report is considered the prevailing information. There is no pre-set sampling frequency: participants can send as many data as they like. The project runs "face-to-face data collection events" mainly in schools, meaning that in some places and for a given time period, data sampling might be more intense. This is also true when and where there has been a particular dissemination event.
