clima-anom 0.7.7

Obtain the climatology and anomalies only for monthly data.

Climatology and Anomalies in Python

Overview

This code provides experimental and simples tools for differents operations on climate data, mainly obtaining climatologies and anomalies values, in addition to others operations such as data extraction from continent, ocean or a shapefile.

Pip install

pip install clima-anom

Data

The data use for examples is in directory data. For complete data see:

TRMM Precipitation L3 daily 0.25x0.25 V7

Example

import os
import clima_anom as ca

data_dir = '..'+os.sep+'data'+os.sep+'3B42_199901_201212.nc'
data = ca.read_netcdf(data_dir,2)

lat = data['lat']
lon = data['lon']
pre = data['prec']

pre_dictionary = ca.data_dictionary(pre)
