Venusian planetary-scale waves observed by Akatsuki LIR: Rossby-Kelvin instability and long-term variation [Data set]

  • 1. ROR icon The University of Tokyo

Description

# Description

This dataset contains time series of the temperature gradient derived from Akatsuki LIR data for each Venusian Year (VY), emission angle, and latitude. The dataset was created by Hiroyuki Koyama at The University of Tokyo.


# File name convention

YYYYMMDD_1VY_aa.a_bbb.b_plot_temp.dat

  YYYYMMDD: Start date of each Venusian Year (VY)
  aa.a: Lower limit of the emission angle range used for deriving the temperature gradient. The range is from aa.a to aa.a+10 degrees.
  bbb.b: Latitude


# File format

Column 1: Elapsed time from the beginning of each VY in unit of hour
Column 2: Elapsed time from the beginning of each VY in unit of day
Column 3: Local solar time of Venus at the observed location in unit of hour
Column 4: Temperature gradient in unit of Kelvin/degree before removing long-term trends
Column 5: Temperature gradient in unit of Kelvin/degree after removing long-term trends
