Create an "Ozone Number Density" PLOT with a CALIPSO L-1B dataset
Posted: Fri Nov 18, 2022 1:31 pm America/New_York
We have created a short script for those users interested in creating "Ozone Number Density" plots from the CALIPSO L1B data.
Go to the link shown below to access the script.
Ozone Number Density
Python script: https://github.com/nasa/ASDC_Data_and_User_Services/blob/main/CALIPSO/CALIPSO_Ozone_Number_Density
Description: Mean ozone number density reported for the temporal midpoint of each range bin in each 20 km horizontal resolution profile (i.e., the average of the ozone number densities reported at the 30th and 31st consecutive single shot profiles for each range bin). Logarithmically interpolated from the 33 standard altitudes levels reported in the lidar level 1B products (Met Data Altitudes) to the 400 standard altitude levels reported in the lidar level 1.5 product (Lidar Data Altitudes) prior to computing the temporal midpoint average. For the version 3 expedited level 1.5 product, modeled atmospheric data is derived from the Global Modeling and Assimilation Office (GMAO) Forward Processing for Instrument Teams (FP-IT) global meteorological product. For the version 1 standard level 1.5 product, Modern Era Retrospective-Analysis for Research (MERRA-2) products are used.
Units: m-3
