Paul David Hamer

Dr. Paul Hamer er forsker på avdelingen By og industri ved NILU.

Han har en doktorgrad i atmosfærisk kjemi fra University of Bristol. Han har over 20 års erfaring med å jobbe innen atmosfærevitenskap og har publisert på et bredt spekter av forskningsemner. Hans kjernekompetanse er i arbeid med numeriske modeller av atmosfæren og landoverflaten og i arbeid med dataassimilering og satellittobservasjoner.

Han har en sterk interesse for luftkvalitet, klimaendringer og landoverflateprosesser. Som sådan har hans nyere forskning fokusert på virkningene som klima og ekstremvær har på overflateflukser (avsetning og utslipp) av luftforurensninger og deres forløpere. Videre har han en sterk interesse i å gi en viktig kobling mellom luftkvalitetsvitenskap og beslutningstakere gjennom sine aktiviteter innen Copernicus Atmospheric Monitoring Service.

Paul er motivert av behovet for å gi vitenskapelig kunnskap til samfunnet, for å hjelpe med beslutningstaking i forhold til luftkvalitetsstyring og klimaendringspolitikk.
