Generic: aircraft data

[2]:

import datetime as dt
import pdbufr

The input BUFR data contains aircraft observations. Each message represents a single measurement of temperature, wind etc. at a given time and (3D) location.

In this notebook we read this data with the generic reader, which is the default reader.

Example 1

Extract all temperature observations.

[3]:

df = pdbufr.read_bufr("aircraft_small.bufr",
    columns=("aircraftFlightNumber", "latitude", "longitude", "pressure", "airTemperature"))
df

Example 2

Getting data for a given flight only:

[4]:

df = pdbufr.read_bufr("aircraft_small.bufr",
    columns=("aircraftFlightNumber", "latitude", "longitude", "pressure", "airTemperature"),
    filters={"aircraftFlightNumber": "UOZDOZ2S"})
df

[4]:

	aircraftFlightNumber	latitude	longitude	pressure	airTemperature
0	UOZDOZ2S	41.45	-75.43	24990.0	216.7

3	UOZDOZ2S	41.67	-76.16	18750.0	222.7

Example 3

Getting data for a given time interval only:

[5]:

df = pdbufr.read_bufr("aircraft_small.bufr",
    columns=("data_datetime", "aircraftFlightNumber",
             "latitude", "longitude", "pressure", "airTemperature"),
    filters={"data_datetime":
               slice(dt.datetime(2009,1,23,13,0), dt.datetime(2009,1,23,13,1))})
df
