Measurements were made at the Indian Institute of Technology Delhi (IIT-Delhi), India. Mixing ratios are reported in parts per billion (ppb). The stationary inlet was located on the roof of a 5-storey building at Block IV, Indian Institute of Technology Delhi campus. \r\n\r\nThe data were collected over three measurement periods (i) winter: 12/01/2018 - 13/02/2018, (ii) pre-monsoon: 26/04/2018 - 05/06/2018 and (iii) post-monsoon: 13/10/2018 - 10/11/2018, by the University of Birmingham.\r\n\r\nThese data were collected as part of the ASAP-Delhi project as part of the Atmospheric Pollution and Human Health in an Indian Megacity (APHH) programme.","keywords":"APHH, ASAP-Delhi, NO, NO2, NOx","publicationState":"published","dataPublishedTime":"2021-03-25T15:32:43","doiPublishedTime":null,"updateFrequency":"notPlanned","status":"completed","result_field":{"ob_id":"https://catalogue.ceda.ac.uk/api/v2/observations/32246/?format=json","dataPath":"/badc/aphh/data/delhi/asap-delhi/bham-nox","oldDataPath":[],"storageLocation":"internal","storageStatus":"online","volume":13558958,"numberOfFiles":5,"fileFormat":"Data are NASA Ames formatted."},"timePeriod":"https://catalogue.ceda.ac.uk/api/v2/times/8847/?format=json","geographicExtent":"https://catalogue.ceda.ac.uk/api/v2/bboxes/2739/?format=json","nonGeographicFlag":false,"phenomena":["https://catalogue.ceda.ac.uk/api/v2/phenomona/41999/?format=json"],"dataLineage":"Data were collected, quality controlled and prepared for archiving by the instrument scientists before upload to the Centre for Environmental Data Analysis (CEDA) for long term archiving.","removedDataTime":null,"removedDataReason":"","language":"English","identifier_set":[],"projects":["https://catalogue.ceda.ac.uk/api/v2/projects/24808/?format=json","https://catalogue.ceda.ac.uk/api/v2/projects/32248/?format=json"],"observationcollection_set":["https://catalogue.ceda.ac.uk/api/v2/observationcollections/32257/?format=json","https://catalogue.ceda.ac.uk/api/v2/observationcollections/32625/?format=json"],"responsiblepartyinfo_set":["https://catalogue.ceda.ac.uk/api/v2/rpis/143453/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/143454/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/143455/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/143456/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/143457/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/143459/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/143460/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/143458/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/168357/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/143466/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/143467/?format=json"],"procedureAcquisition":"https://catalogue.ceda.ac.uk/api/v2/acquisitions/32249/?format=json","procedureCompositeProcess":null,"procedureComputation":null,"permissions":[{"ob_id":"https://catalogue.ceda.ac.uk/api/v2/observations/2522/?format=json","useLimitation":null,"accessConstraints":null,"accessCategory":"registered","accessRoles":null,"label":"registered: None group","licenceURL":"http://www.nationalarchives.gov.uk/doc/open-government-licence/version/3/","licenceClassifications":"any"}],"discoveryKeywords":[{"ob_id":1138,"name":"NDGO0003"}]}
