This archive contains the many files and instructions for obtaining surface 
weather data

1 file: TRAMP_merge_meas_mod_version20211230.csv 

The merge of 1-minute data from all TRAMP measurements for all times is a 
csv file..

The header gives the name of the variable and its units. Note that the 
extreme values for observed OH and HO2 have been removed. The merge also 
contains the OH and HO2 modeled with RACM (S4). "-9999" indicates no 
measurement. These data were used to plot Fig. 1C and 1D. 


18 files: TRAMP_2006MMDD_version_20211211.csv

The merges of 5-Hz data from TRAMP measurements for only a few hours around 
the times of the extreme OH and HO2 are csv files. MMDD is the month and day 
that the file record starts, but each file typically runs from morning of the 
first day to the morning of the next day. The header gives the names of th
e variables and their units. TRAMP measurements in the 1-minute merge are 
interpolated to 5-Hz. In addition to these measurements and the 5-Hz OH and 
HO2 measurements, are the following variables:

  GTHOS_Cal: "1" indicates an hourly period of instrument testing that started
    at 30 minutes past each hour.

  GTHOS_OHRay: Counts/0.2s is the OH scattering signal caused by rain entering 
    the GTHOS inlet.

  GTHOS_OnLine: "1" indicates times when the laser wavelength is tuned to the 
    OH absorption line enabling the measurements of OH and HO2. "0" indicates 
    background measurements.

  GTHOS_Scan: "1" indicates periods when the laser wavelength is being scanned, 
    producing the OH spectrum around the line that is being used.

 "-9999" indicates no measurement.


2 GOES movies of Infrared Water Vapor and Visible for Houston area

The two avi files contain movies of the Houston area. Intermixed are the 
Infrared Water Vapor and the Visible channels. The dates covered in each file 
are listed in the file name. These data are used in Table S1.
