OMI Ozone Time Series Data

OMI Satellite Level 3e daily averaged ozone data have been obtained from the NASA Space-Based Measurement of Ozone and Air Quality Website gridded at 0.25 x 0.25 degrees. OMI data availability cover October of 2004 to present. The latest data have about two days latency.

This tool allows OMI Ozone time series data to be retrieved for a specific latitude and longitude coordinate and date range. The resulting dataset can be generated in either CSV-text or an XY-Plot in PNG format. For text-based datasets, missing data values can be filtered from the text dataset by setting Include Missing Data to NO. The ozone values returned are from the nearest 0.25 gridded lat and lon point in the OMI dataset. Data are rendered in a new browser window or tab (browser setting specific).
