Getting started

Single plot

Draw a single figure in command line.

The following command draws a figure for 2m temperature using CMA-GFS data in CMA-HPC.

python -m cemc_plots_kit draw \
  --system-name cma_gfs \
  --plot-type t_2m \
  --start-time 2024111300 \
  --forecast-time 24h \
  --work-dir .

The command will generate an image file named t_2m_2024111300_024.png in current directory.

Batch plot

Draw a batch of figures using a task file.

Create a task file named task.yaml with content:

runtime:
  base_work_dir: .

source:
  data_dir: /g3/COMMONDATA/OPER/CEMC/GFS_GMF/Prod-grib/{start_time_label}/ORIG

system_name: CMA-GFS

time:
  start_time: 2024111300
  forecast_time: 48h
  forecast_interval: 6h

plots:
  height_500_mslp: on
  rain_24h: on

Execute the following shell command to draw figures:

python -m cemc_plots_kit task --task-file ./task.yaml

When the command is executed, there are 14 image files in output directory:
