Hello.

Harmony seems an exciting service same as appeears.

But I have a general question.

does not the Appears service have similar goals? I mean generating ARD data by providing transformation, reprojection and so on

Hi @akasom,

You're correct that both Harmony and AppEEARS offer services for performing transformations to generate Analysis Ready Data (ARD), but they are somewhat different in their approach and functionality.

AppEEARS is a standalone application that provides a user-friendly interface for processing datasets. It applies consistent templates to each dataset, making it easy to handle and interpret outputs. Additionally, AppEEARS includes built-in visualization tools, which allow users to quickly explore and analyze their results without requiring external software.

Harmony, on the other hand, is a modular framework consisting of independent services that can be executed individually or combined into workflows. This allows for more customization of outputs, enabling users to tailor processing pipelines to their specific needs. This flexibility does come with added complexity, requiring users to have a slightly deeper understanding of the available services and their configurations.

Additionally, the datasets available through Harmony and AppEEARS currently do not overlap. Each offers access to different datasets from various Distributed Active Archive Centers (DAACs), reflecting the specific needs of different user communities.

Thanks for your complete answer
