Ramanathan (1988) notes that both water and ice clouds, when formed at cold lower stratospheric temperatures, are extremely efficient in enhancing the atmospheric greenhouse effect.
Ramanathan (1988) sinalou que tanto as nubes de xeo coma a auga, cando se forman ás frías temperaturas da estratosfera, son extremadamente eficientes en potenciar o efecto invernadoiro atmosférico.
