The Air Quality and Assessment program for the Arizona Department of Environmental Quality ( ADEQ ) is seeking to procure a ceilometer to provide automated measurement of the planetary boundary layers ( PBL ) and provide the mixing layer height ( MLH ) through an internal algorithm and with the capability of linking into Hampton University Unified Ceilometer Network ( UCN ). Equipment is to meet the requirements notated in 40 CFR Part 58 Appendix D section 5 ( b ). The Air Quality and Assessment program for the Arizona Department of Environmental Quality ( ADEQ ) is seeking to procure a ceilometer to provide automated measurement of the planetary boundary layers ( PBL ) and provide the mixing layer height ( MLH ) through an internal algorithm and with the capability of linking into the Hampton University Unified Ceilometer Network ( UCN ). Due to the value of the full backscatter profile , EPA , in conjunction with Hampton University , and NASA , developed a new data system for the collection , storage , and retrieval of ceilometer data called the Unified Ceilometer Network ( UCN ). The UCN is an open network designed to automatically retrieve and store ceilometer profile backscatter from participating ceilometers . A number of options are available for data collection based on the IT requirements of the partner monitoring agency . Equipment is to meet the requirements notated in 40 CFR Part 58 Appendix D section 5 ( b ).
