About 晴天鍾 - 天文工具集

晴天鍾按照經緯度顯示天氣資料，日落日出，月落月出等資料，主要用於天文觀測。

晴天鍾是一系列天氣預測產品的總稱，它們主要提取於美國國家大氣海洋局/氣候環境預測局(NOAA/NCEP)的“全球預測系統”(Global Forecast System, GFS)數值模式。晴天鍾在2005年7月作為國家天文臺宇宙驛站伺服器的實驗產品開始運作，並在2008年及2011年進行了大規模的翻新。目前它由中國科學院上海天文臺中國天文科普網提供硬體及網路支援。

除去天氣服務，晴天鍾還提供：
1. 天象預報服務（與位置無關）
2. 光汙染地圖、衛星雲圖
3. 恆星、行星、衛星的升落時間
4. 天文交流論壇
