I have a dataset of horizontal polygons, which have a vertical distance of 175 meters to each other. These polygons mark certain areas. I would like to have one polygon that covers all the area and doesn't have these blank stripes in it. Basically I want to sort of buffer the polygons, but only vertically, so that they connect to one big polygon.

Does someone know how to do this?
Here is a sample of the data:
