MAIA Geographic Information Visualization Tool (GIVT)

The MAIA Geographic Information Visualization Tool (GIVT), developed at the Jet Propulsion Laboratory using the open-source Multi-Mission Geographic Information System (MMGIS) software, allows users to visualize layers of geographical information related to the MAIA mission. GIVT features several static layers, such as target area bounding boxes, maps of ancillary geographic information (e.g., population and urban density), and the location and type of surface PM monitors. Additionally, GIVT enables the visualization and download of dynamic, quality-controlled daily-averaged PM measurements from surface monitors located in the PTAs. To learn how to use this tool, click on the "help" (?) button in the bottom left corner of the map.

MAIA acknowledges the contributions of various organizations that provide in-situ PM monitoring data, either directly or through publicly available resources. These include the following:
