DATA & FILE OVERVIEW
---------------------

1. File List:

    A. Allen_Aerosol_lightning_paper_v7.pdf
       PDF containing version of paper submitted to JGR. 


    B. Filename: Conv_metrics.txt 
        Text file containing convective metrics for 5362 Amazon Basin deep convective systems during 2012-2017 time period.    
	The metrics are date (YYYYMMDD), time of first retrieval within system (bHHMMSS), time of last retrieval within system (eHHMMSS), 
	longitude at center of system (DLONPT), latitude at center of system (DLATPT), IMERG rain-rate (PRECIP), 
	STARNET flash count (FLASHES), ERA5 CAPE (CAPE), Merra-2 AOD (AOT),centroid of ice water content (CEN_IWC), 
	centroid of radar reflectivity (CEN_ZE, mid-tropospheric relative humidity from ECWMF (RH), 
	lower tropospheric static stability (LTSS), and CALIOP aerosol type (TYPE_A) 


    C. Filename: Conv_metrics.ncf
       NetCDF file containing 5362 profiles of Cloud Sat radar reflectivity (Ze) and ice water content (IWC) on 125 vertical layers at altitudes
        given in variable Height.  The time and location of each profile is specified in Conv_metrics.txt file. 


    D. Filename: aeronet_vars.ncf
       This data set was used to create Figures 5 and 6 and Tables 1-3 in the aforementioned manuscript. 
       NetCDF file containing flash rates (flashes_starnet), rain-rates (precip_imerg), and values of AOD (aod_aeronet) corresponding to
       the AERONET sites listed in Tables 2 and 3 of aforementioned manuscript.  
       The temporal resolution of the various data sets is 10-minutes for flashes, 30-minutes for precipitation, and 12-18 UT mean for AOD. 
       Values are available for at least one site on 732 days. 
       
    E. Filename: Figure2.tar
       Contains names of CALIPSO data sets and IDL code needed to generate Figure 3. 
        
       
2.   Relations of files to Figures and Tables in manuscript. 

       The Figure 3 caption contains the information needed to generate Figure 3.  

       Figure 4 was created as follows:
       1) MERRA-2 AOD, ERA5 CAPE, IMERG precipitation, and STARNET flashes were aggregated onto a 1x1 grid at a 30-minute temporal resolution. 
       2) 30-minute periods with flashes and precipitation were extracted. 
       3) The difference in median values of each quantity are shown between periods when the AOD exceeded 
       the 70th percentiles and between periods when it was less than the 30th percentile. 
       
       The variables in aeronet_vars.ncf were used to create Figures 5 and 6 and Tables 1-3 in the aforementioned manuscript. 
       Conv_metrics.txt and Conv_metrics.ncf were used to create Figures 7-10 in manuscript.
