Southern Oxidant and Aerosol Study NSF funded $4 million in individual investigator proposals NSFs overall investment in SOAS is $8+ million EPA originally planned to fund 8 proposals, but increased investment to 14 proposals NOAAs commitment to fly the P3 for SENEX was an important impetus SOAS is unique as a grass roots field campaign One of my personal favorite SOAS facts: EPA funded a university scientist to fly an instrument on NOAAs plane REgional Investigation of Local and Long-range ChemistrY (REILLY) Smyrna RTP Look Rock CTR / flux

The National Electric Energy Data System (NEEDS) is the database of existing and planned-committed units which are modeled (as understood by EPA) that are currently operational in the electric industry are termed as existing units. Units that are not currently operating but are firmly anticipated to be operational in the future, and have either broken ground (initiated construction) or secured financing are termed planned-committed.
