Installation

pip install radar-data

Examples

import radar

# Get the absolute path of the .nc file, reader automatically gets -V, -W, etc.
file = os.path.expanduser("~/Downloads/data/PX-20240529-150246-E4.0-Z.nc")
sweep = radar.read(file)

# It also works with providing the original .tar.xz or .txz archive
file = os.path.expanduser("~/Downloads/data/PX-20240529-150246-E4.0.txz")
sweep = radar.read(file)

# NEXRAD LDM data feed, simply supply any of the files, the reader reads sweep_index=0 by default
file = os.path.expanduser("~/Downloads/data/KTLX/861/KTLX-20250503-122438-861-1-S")
sweep = radar.read(file)

# The reader finds others in ~/Downloads/data/KTLX/861/ to get to sweep_index=1
file = os.path.expanduser("~/Downloads/data/KTLX/861/KTLX-20250503-122438-861-7-I")
sweep = radar.read(file, sweep_index=1)

# NEXRAD complete volume
file = os.path.expanduser("~/Downloads/data/KTLX/20250503/KTLX20250503_122438_V06")
sweep = radar.read(file, sweep_index=1)

DataShop

A data server for multi-threaded reading. An example use case would be to abstract the file reading backend to this service so that multiple requests can be pipelined.

usage: datashop [-h] [-c COUNT] [-d DIR] [-H HOST] [-p PORT] [-t TEST] [-v] [--delay] [--version] [source ...]

Datashop

Examples:
    datashop -v settings.yaml
    datashop -v -H 10.197.14.52 -p 50001 -c 4 -t /mnt/data/PX1000/2024/20241219/_original

positional arguments:
  source                configuration

options:
  -h, --help            show this help message and exit
  -c COUNT, --count COUNT
                        count
  -d DIR, --dir DIR     directory
  -H HOST, --host HOST  host
  -p PORT, --port PORT  port
  -t TEST, --test TEST  test using directory
  -v                    increases verbosity
  --delay               simulate request delays
  --version             show program's version number and exit
