Da Vinci glow

The experts predicted that a ‘da Vinci glow’ would be visible around the new moon on May 19, 2023.

  • The da Vinci glow is a phenomenon in which the crescent moon is on the horizon, but the outline of a full moon is visible.
  • The phenomenon usually happens close to sunset.
  • On some days, this happens after the sun sets, and the sky is dark but not completely dark.
  • This glow is also called earthshine, since it occurs due to light reflected from the earth and not the sun.
  • The earthshine is the sunlight first reflected by the earth’s surface, and then it’s reflected by the moon before it reaches our eyes.
  • Since it is reflected twice, it is dimmer than the visible part of the moon and thus appears as a faint glow, called the da Vinci glow.
  • Earth's clouds are the primary source of this earthshine.

According to NASA, earthshine makes night on the moon 50-times brighter than a full-moon night on the earth.

  • Leonardo da Vinci (1452-1519) was the first person to describe the phenomenon in the 16th century and it was named after him.
  • Before da Vinci’s theory, the ‘ashen glow’ of the moon was often called the ‘old moon in the new moon’s arms’.

NITI Aayog's Health Index

NITI Aayog’s annual ‘health index’ for the COVID year of 2020-21 was released.

  • The annual health index was launched by the NITI Aayog in 2017.
  • The Health Index is a weighted composite index based on 24 indicators grouped under the domains of ‘health outcomes’, ‘governance and information’, and ‘key inputs/ processes’.
  • The health index measures the performance of states and UTs on a weighted composite score on 2 parameters –
    • Incremental performance (year-on-year progress)
    • Overall performance.
  • The states and UTs are categorised separately as ‘larger states’, ‘smaller states’ and UTs and they are then ranked based on their scores.
  • The fifth health index (2020-21) report has not been made public yet.
  • COVID year 2020-21 assessment report

Global Greenhouse Gas Watch (G3W)

The World Meteorological Congress has approved a new greenhouse gas (GHG) monitoring initiative in a landmark decision.

  • Global Greenhouse Gas Watch (G3W) is an initiative coordinated by World Meteorological Organisation (WMO).
  • G3W aims to establish internationally coordinated monitoring of greenhouse gas fluxes (top-down) to support the provision of the UNFCCC parties and other stakeholders.
  • The new global GHG watch will fill critical information gaps and provide an integrated and operational framework.
  • The framework will bring all space-based and surface-based observing systems, as well as modelling and data assimilation capabilities, under one roof.
  • Components - There are 4 main components of G3W
    1. Surface-based and satellite- based observations.
    2. Prior observations.
    3. Near-real time international exchange of input and output data.
    4. Global high-resolution modelling/data assimilation.
  • Output - The system will provide sustained delivery of monthly global estimates of net GHG fluxes into and out of the atmosphere at a 100 by 100 km resolution.
  • Benefits - Improved evaluation of sources and sinks of greenhouse gases.
  • Indicate their association with the biosphere, the ocean and the permafrost areas.
