AgenciBr

The objective is create a package that help to usa data of Agencia Nacional de Águas (ANA), Instituto Nacional de Meteorolhttps://ftp.cptec.inpe.br/modelos/tempo/MERGE/GPM/Rozante_et.al.2020.pdfogia (INEMET), Merge, Brazilian Daily Weather Gridded Data (BR-DWGD) and Instituto de Hidrología, Meteorología y Estudios Ambientales (IDEAM). All the data above is from Brazil, minus the IDEAM that is from Colombia.

• ANA [https://www.gov.br/ana/pt-br] or [https://www.snirh.gov.br/hidroweb/apresentacao]

• INEMET [https://portal.inmet.gov.br]

• MERGE [http://ftp.cptec.inpe.br/modelos/tempo/MERGE/GPM/DAILY/] This method is reported at pdf Performance of precipitation products obtained from combinations of satellite and surface observation, explaining the method called Merge to consider station data and satelite

• BR-DWGD [https://github.com/AlexandreCandidoXavier/BR-DWGD]

• IDEAM [http://www.ideam.gov.co]

Usage

pip install AgenciBr

In python:

Import Ana

from AgenciBr import Ana.Ana
data = Ana.Ana('path file')

""" Properties """
data.dataset # return the dataset

data.code #Return the 

data.startdate #return the first date from dataset

data.enddate  #return the end date from dataset

data.len #return the length from dataset

data.type_data #return the data informations (precipitation, temperature, t_maxmin, wind, ...)

data.type #return if data is original, format1, format2 ...

Import Inemet

from AgenciBr import Inemet

data = Inemet.Inemet('path file')

Import Merge

from AgenciBr import Merge

data = Merge.Merge('path file')

Import Alexandre

from AgenciBr import Alexandre

data = Alexandre.Alexandre('path file')

Import Ideam

from AgenciBr import Ideam

data = Ideam.Ideam('path file')

Suported functions

Merge	[ ]	[ ]	[ ]	[ ]
Alexandre	[ ]	[ ]	[ ]	[ ]
Ideam	[ ]	[ ]	[ ]	[ ]

From internal function we construct function1, functon2

Internal functions

Format1

We work with distints data and dataframe models, bacause this, was create the function format1 in each agenci. This function have three param:

• Comma_to_dot: change the comma of all file to dot and to float number
• grow: Change the dataframe from de lower to larger
• years: is a vector of two numbers (year1, year2) that you wish be the start and end, the year can be the future

The principal objective of this function is

1. put date that can be jumped
2. organize the file from to smaler to larger based in time
3. Change the ',' to '.'
4. Remove same values from file
5. Change the name of time variable to time
6. padronize a file to work with Ana, Inemet, Merge and etc
7. have option to select a series of year start and year end. The date that not exist, are created and set NaN

Format2

We work with datasets, to padronize, we create the function format2 that exists only when you are working with dataset files.
