Abstract: According to one embodiment, a method, computer system, and computer program product for collecting aerosol samples is provided. The present invention may include, responsive to one or more sample collection criteria being met, collecting an aerosol sample in at least one of one or more collection media including at least one liquid collection medium, wherein collecting the aerosol sample comprises propelling air, via an air pump, through a collection medium of the one or more collection media for a duration equal to a sample integration time; responsive to detecting that a sampler liquid level in at least one liquid collection medium is below a threshold, raising the sampler liquid level in the at least one liquid collection medium to meet the threshold; and transmitting a message alerting one or more users that the aerosol sample has been collected.

Abstract: Methods, systems and computer program products for determining an accurate flow rate based on limited observations are provided. Aspects include receiving a limited sample of flow rate data associated with a test site of a test river. Aspects also include determining topographical characteristics of the test site. Aspects also include determining a plurality of similar tested sites and generating a test site rating curve based on a combination of the limited sample of flow rate data and sufficient flow rate data associated with one or more of the plurality of similar tested sites. Aspects also include obtaining a stage reading associated with the test site from a sensor disposed at the test site. Aspects also include determining a flow rate of the test site based on the stage reading and the test site rating curve.
