CERES Ordering Tool Help


Introduction

An ordering tool is provided for obtaining data specific for your needs. Once the following page appears, you will be given the choices for your selected product. There are several criteria and options the tool uses to select your data of interest, render browse images, and obtain the data. Information pertaining to each of these areas are provided below.

1. Data Selection   2. Browsing Data   3. Obtaining Data
4. Checking on an Order   5. NetCDF Format

1. Data Selection

The Data Selection page is provided to allow for specific selection of the data found with the product. Customize your data by choosing the parameters of intererest, temporal resolution, spatial resolution, satellite and time range of the data.

Parameters

The parameter section (Fig 1-2) will first appear with a list of main categories for data available within this product. Each is preceded by a select button and a Image: Right Arrow Icon folder icon.

Note: Clicking on the Image: Information Icon provides detailed explanations, definitions and example plots where applicable.

  • Clicking the select button will select all parameters available within this category or individual parameter for browsing and/or ordering.
  • Clicking the Image: Right Arrow Icon folder icon will expand the category for a more detailed level of the available parameters.
  • When applicable, columns are provided for selection/deselection of more detailed parameter selection. As in the following example, the Image: Clear-Sky Button and Image: All-Sky Button refer to clear-sky and all-sky sub categories.

Temporal Resolution

The temporal resolution section (Fig 1-3) provides the resolutions available within this product.
For this example, Monthly Means and Climate are simple selections.

Spatial Resolution

The spatial resolution section (Fig 1-4) provides the resolutions available within this product.
For this example, Zonal and Global means are simple selections.
Regional provides the ability to subset based on the rectangle coordinates either typed into the bounding boxes labeled "North", "South", "East", and "West".

As an alternative, click the Image: Google Map Icon Map icon to expand a global Goo gle map (Fig 1-5). Using your shift key and mouse, generate a bounding box for which the coordinates are automatically calculated.
Or, you may type the coordinates in the bounding boxes labeled "North", "South", "East", and "West", then click "Apply Values to the Map" to see the bounding box on the map.

Satellite

The satellite section (Fig 1-6) provides the satellite available for this product. For this example, only Terra data is available. For other products, Terra and Aqua data are options.

2. Browsing Data

By selecting a Spatial Resolution and "Plot Data" at the bottom of the data selection page, one of several types of plots may be rendered. Select the image of interest. The data from the image may be downloaded in ASCII as needed. If all of the data is needed, return to the Data Selection page and select "Get Data" at the bottom of the page.

Regional

With the The Regional browse images will be rendered (Fig 2-1).
Each row is a specific parameter choosen in the data selection page.
Each column represents each month throughout the selected time range.

Downloading ASCII Data Files

By selecting the "Plot Data" at the bottom of the data selection page (Fig 1-1), one of the three data type browse images will be rendered (Fig 2-7). All data images have a "Save Data as ASCII file" button for downloading of the data into an formatted ASCII file. The ASCII data file provided contains all information for recreating the data image with alternate software.

As an example, the "Save Data as ASCII file" button is shown for each of the 3 data plot types:

  • regional data image (ref 1)
  • zonal data image (ref 2)
  • global data images (ref 3)

3. Obtaining Data

Data can be obtained from the CERES Ordering Tool in one of two ways; in netCDF file(s) via "Get Data" immediate processing for small orders and through "Add to Cart", a shopping cart method for multiple and large orders.

Ordering netCDF Data Files, Get Data option

If the data selected totals less then 2GB, by selecting the "Get Data" at the bottom of the data selection page, the order will be automatically placed and the Order Summary page will be rendered with a download button to obtain the file (Fig 3-4).
If the data selected totals more then 2GB, then an information page will be rendered asking if there is a desire to reduce the size of the data selected or add the data to the shopping cart.

Ordering netCDF Data Files, Shopping Cart option

By selecting the "Add to Cart" at the bottom of the data selection page, the size of the order will be rendered under the button (Fig 3-1). To inspect order instances in the Shopping Cart, a tab is provided at the top of the data selection page.

Image: Ordering Data view
Fig 3-1: Ordering Data view

By selecting the "Shopping Cart" tab at the top of the data selection page, a shopping cart page will display all data instances added to the shopping cart ready to be ordered.

Image: Shopping Cart view
Fig 3-2: Shopping Cart view

Order Summary Page

By selecting a "Get Data" with orders less then 2GB at the bottom of the data selection page or selecting a specific order within a a status view the Order Summary Page will be rendered (Fig 3-4).

  • An overview of the data in your order (ref 1).
  • Note: data files will be deleted within 15 minutes. Up to 10GB of data can be ordered through this page (ref 2).
  • A table of the files contained in the order (ref 3). For each file, there is a file size limit of 2GB.
  • A download button for each file is provided (ref 4). If the file needs a few seconds to process, this will show as processing.
  • A table of the dimensions with addtional attribute information (ref 5).
  • A table of the parameters with addtional attribute information (ref 6).

4. Checking on an Order

Upon return to the Ordering Tool, you may log in to view the status of orders placed.

My Orders

By selecting the "My Orders" tab at the top of the data selection page, an order status page will display all data instances ordered. A column shows the submitted date of the order, when the order will expire, and the processing status of the order.

Fig 4-1: Ordering Status (all) view

Order Status

By selecting the linkable "Order Name" within the Order Status table (Fig 4-1), an order status page for an individual order will display. More specific information about the order is displayed. By selecting the linkable "Product Information" within the individual order status page, the Order Summary page will be rendered with a download button to obtain each of the files needed in the order (Fig 3-4).

5. NetCDF (network Common Data Form)

The data produced in an order are in netCDF format. NetCDF (network Common Data Form) is a self-describing file format that can more easily read using developed libraries for making the files machine independent. To obtain more information about netCDF files and libraries for download, please visit UNIDATA Software for Manipulating or Displaying NetCDF Data link to external site
