GK2A Satellite Data API

This API Service is to provide GK2A satellite data and secondary processed data which is expected to be used in various areas

1. Introduction

Request GK2A satellite data and secondary processed data (cloud albedo, cloud motion, and etc.) Provide clip interesting regions via latitude and longitude, and resolution manipulation)

• url: `http://apialpha.60hz.io/gk2a/`

• output type: `json`

2. Request Parameters

Arguments	Required	Description
variable	True	Name of data interested in
obs_datetime	True	Datetime of data interested in (YYYYMMDDhhmm)
ullatitude	False	Latitude at upper-left corner
ullongitude	False	Longitude at upper-left corner
lrlatitude	False	Latitude at lower-right corner
lrlongitude	False	Longitude at lower-right corner
resolution	False	Resolution reduction/magnification ratio compared to original data

3. Response

Keys	Description
dtype	Type of data
shape	Original shape of data, decoded result of ‘data’ should be reshpaed by this
data	8-bit encoded numpy array data, should be decoded using ‘base64’ or other libraries

Sample code (python3)

import requests
import base64
import numpy as np

url = 'http://apialpha.60hz.io/data'
params = {'variables':'cloudalbedo', 'obs_datetime':'202111180550'}

response = requests.get(base_url, params=params)
data = response.json()
result = np.frombuffer(
   base64.decodebytes(data['data'].encode('utf8')),
   dtype=data['dtype']
).reshape(data['shape'])

print(result)
