NASA/JPL's Webification

All of NASA/JPL's science data is available to the public. Webification (w10n) is an open source NASA/JPL data access framework that enables developers to easily access data in web-friendly formats for visualizations like this:

Webification simplifies use of the large and often complex data files published by NASA's Distributed Active Archive Centers, like PO.DAAC. The PO.DAAC w10n Service is open source software, that bridges the gap between Earth science data formats like NetCDF, HDF4 & HDF5 to JSON and XML.

Getting Started

1, Explore the interactive tutorial here

2, Test our our live API here:

# Open to explore in your web browser and note the available attributes:
http://54.212.253.164/data/GRACE.CSR.LAND.RL05.DS.G200KM.nc/?output=html

# bash
# - Get Metadata with '/'
curl "http://54.212.253.164/data/GRACE.CSR.LAND.RL05.DS.G200KM.nc/lat/?output=json"
# - Get 100 datapoints with '[0:100]'
curl "http://54.212.253.164/data/GRACE.CSR.LAND.RL05.DS.G200KM.nc/lat\[0:100\]?output=json"

# python
import requests
# - Get Metadata with '/'
requests.get('http://54.212.253.164/data/GRACE.CSR.LAND.RL05.DS.G200KM.nc/lat/?output=json')
# - Get 100 datapoints with '[0:100]'
requests.get('http://54.212.253.164/data/GRACE.CSR.LAND.RL05.DS.G200KM.nc/lat[0:100]?output=json')

// Javascript
// - Get Metadata with '/'
http.get("http://54.212.253.164/data/GRACE.CSR.LAND.RL05.DS.G200KM.nc/lat/?output=json", function(res) {
  res.on("data", function(chunk) {
    console.log("data: " + chunk);
  });
});
// - Get 100 datapoints with '[0:100]'
http.get("http://54.212.253.164/data/GRACE.CSR.LAND.RL05.DS.G200KM.nc/lat[0:100]?output=json", function(res) {
  res.on("data", function(chunk) {
    console.log("data: " + chunk);
  });
});

3, Spin up a webification machine of your own (AMI ID: ami-3eef740e, named: 'w10n-reinvent' in US-West-2 ) with w10n pre-configured. Notes:

• Suggested instance type: m1.medium
• Security Group should allow inboud traffic from only ports 22 & 80
• Setup your own server simply by downloading & unzipping this API:
  • https://s3-us-west-2.amazonaws.com/w10n/taiga-1.6.6-linux-x86_64-b.tar.gz

4, SSH into your instance

#log into the machine you just spun up
> ssh -i <your ssh key.pem> ubuntu@<address of the machine you just created>

# Configure this new w10n server to use port 80
ubuntu$ sudo ./taiga/taiga-1.6.6-linux-x86_64-b/bin/taiga-service config -p 80 -d /vol/data

# Start your server
ubuntu$ sudo ./taiga/taiga-1.6.6-linux-x86_64-b/bin/taiga-service start

# Verify that your server is running & logout
ubuntu$ curl localhost
ubuntu$ exit

## Now point your browser to the <address of the machine you just created> and interact with your favorite API!
